- This is an MDMA sysnthesis I OCR's out of my copy of _Secrets of
- Methamphetamine Manufacture_, which will probably end up being the one
- that I put in the next revision of my MDMA FAQ. I thought I'd also post
- it as a separate file as well.

- MDMA Synthesis: Bromosafrole method
- Scanned fom _Secrets of Mthamphetamine Maufacture_
-
-
- A good alternative to the Ritter reaction is a two step procedure
- first reacting safrole with hydrobromic acid to give 3,4-methylenedi-
- oxyphenyl-2-bromopropane, and then taking this material and reacting
- it with either ammonia or methylamine to yield MDA or MDMA
- respectively. This procedure has the advantages of not being at all
- sensitive to batch size, nor is it likely to "run away" and produce a
- tarry mess. It shares with the Ritter reaction the advantage of using
- cheap, simple, and easily available chemicals.
-
- The sole disadvantage of this method is the need to do the final
- reaction with ammonia or methylamine inside a sealed pipe. This is
- because the reaction must be done in the temperature range of 120-
- 140 C, and the only way to reach this temperature is to seal the
- reactants up inside of a bomb. This is not particularly dangerous, and
- is quite safe if some simple precautions are taken.
-
- The first stage of the conversion, the reaction with hydrobromic
- acid, is quite simple, and produces almost a 100% yield of the bromi-
- nated product. See the Journal of Biological Chemistry, Volume 108
- page 619. The author is H.E. Carter. Also see Chemical Abstracts
- 1961, column 14350. The following reaction takes place:
-
- [ Structural diagrams deleted]
-
- To do the reaction, 200 ml of glacial acetic acid is poured into a
- champagne bottle nestled in ice. Once the acetic acid has cooled
- down, 300 grams (200 ml) of 48% hydrobromic acid is slowly added
- with swirling. Once this mixture has cooled down, 100 grarns of
- safrole is slowly added with swirling. Once the safrole is added, the
- cheap plastic stopper of the champagne bottle is wired back into
- place, and the mixture is slowly allowed to come to room temperature
- with occasional shaking. After about 12 hours the original two layers
- will merge into a clear red solution. In 24 hours, the reaction is done.
- The chemist carefully removes the stopper from the bottle, wearing
- eye protection. Some acid mist may escape from around the stopper.
-
- The reaction mixture is now poured onto about 500 grams of
- crushed ice in a 1000 or 2000 ml beaker. Once the ice has melted, the
- red layer of product is separated, and the water is extracted with about
- l00 ml of petroleum ether or regular ethyl ether. The ether extract is
- added to the product, and the combined product is washed first with
- water, and then with a solution of sodium carbonate in water. The
- purpose of these washings is to remove HBr from the product. One
- can be sure that all the acid is removed from the product when some
- fresh carbonate solution does not fizz in contact with the product.
-
- Once all the acid in the product is removed, the ether must be
- removed from it. This is important because if the ether were allowed
- to remain in it, too much pressure would be generated in the next
- stage inside of the bomb. Also, it would interfere with the formation
- of a solution between the product and methylamine or ammonia. It is
- not necessary to distill the product because with a yield of over 90%,
- the crude product is pure enough to feed into the next stage. To
- remove the ether from the product, the crude product is poured into a
- flask, and a vacuum is applied to it. This causes the ether to boil off.
- Some gentle heating with hot water is quite helpful to this process.
- The yield of crude product is in the neighborhood of 200 grams.
-
- With the bromo compound in hand, it is time to move onto the
- next step which gives MDA or MDMA. See Chemical Abstracts
- 1961, column 14350. Also see Journal of the American Chemical
- Society, Volume 68, page 1805 and Journal of the Chemistry Society,
- part 2 1938, page 2005. The bromo compound reacts with ammonia
- or methylamine to give MDA or MDMA:
-
- [ Sructural diagram deleted ]
-
- To do the reaction, 50 grams of the bromo compound is poured
- into a beaker, and 200 ml of concentrated ammonium hydroxide (28%
- NH3) or 40% methylamine is added. Next, isopropyl alcohol is added
- with stirring until a nice smooth solution is formed. It is not good to
- add too much alcohol because a more dilute solution reacts slower.
- Now the mixture is poured into a pipe "bomb." This pipe should be
- made of stainless steel, and have fine threads on both ends. Stainless
- steel is preferred because the HBr given off in the reaction will rust
- regular steel. Both ends of the pipe are securely tightened down. The
- bottom may even be welded into place. Then the pipe is placed into
- cooking oil heated to around 130 C. This temperature is maintained
- for about 3 hours or so, then it is allowed to cool. Once the pipe is
- merely warm, it is cooled down some more in ice, and the cap
- unscrewed.
-
- The reaction mixture is poured into a distilling flask, the glass-
- ware rigged for simple distillation, and the isopropyl alcohol and
- excess ammonia or methylamine is distilled off. When this is done,
- the residue inside the flask is made acid with hydrochloric acid. If
- indicating pH paper is available, a pH of about 3 should be aimed for.
- This converts the MDA to the hydrochloride which is water soluble.
- Good strong shaking of the mixture ensures that this conversion is
- complete. The first stage of the purification is to recover unreacted
- bromo compound. To do this, 200 to 300 ml of ether is added. After
- some shaking, the ether layer is separated. It contains close to 20
- grams of bromo compound which may be used again in later batches.
-
- Now the acid solution containing the MDA is made strongly basic
- with lye solution. The mixture is shaken for a few minutes to ensure
- that the MDA is converted to the free base. Upon sitting for a few
- minutes, the MDA floats on top of the water as a dark colored oily
- layer. This layer is separated and placed into a distilling flask. Next,
- the water layer is extracted with some toluene to get out the remaining
- MDA free base. The toluene is combined with the free base layer, and
- the toluene is distilled off. Then a vacuum is applied, and the mixture
- is fractionally distilled. A good aspirator with cold water will bring
- the MDA off at a temperature of 150 to 160 C. The free base should
- be clear to pale yellow, and give a yield of about 20 ml. This free base
- is made into the crystalline hydrochloride by dissolving it in ether and
- bubbling dry HCl gas through it.

- According to J-Forensic-Sci 35(3):675-697 this isn't the best method of
- making methoxylated amphetamine derivatives. The author claims that
- yields are low, synthing the intermediate is time consuming (although
- so is synthing MD-P2P), and potentially hazardous -- I don't know why
- its hazardous, but the author references ANALOG 9(3):1-10 which
- is an article by Hansson, R.C. entitled "Clandestine Laboratories Production
- of MDMA."
-
- It is suggested that the synths using cyanoborohydride, aluminum amalgam,
- borohydride or Raney Ni catalysis from MD-P2P would be more likely to be used.
- The two former ones are preferred as the borohydride method has a lower yield
- and the catalysis requires the construction or purchase of a hydrogenation
- unit.
