- Synthesis of Methylaminorex: US Patent #3,161,650
-
- A mixture of 300cc of methanol and 50cc of water is used to dissolve
- about 35g (.187 mole) of 2-amino-1-phenyl-1-propanol hydrochloride and 16.9g
- (0.411 mole) of sodium acetate. To this solution there is added a
- solution of 21.6g (0.206 mole) of cyanogen bromide in 200cc of methanol.
- The mixture is stirred for one half hour at room temperature and then
- concentrated under vacuum to remove the methanol. The residue is taken
- up in water and the resulting aqueous solution is made strongly basic with
- 10% sodium hydroxide and then saturated with potassium carbonate. The
- resulting precipitate of the crude product is filtered off, washed twice
- with water and dried. The yield of 2-amino-4-methyl-5-phenyloxazoline if
- 12g (m. 155.5-158.5 degrees). After recrystallization from benzene, the
- product melts at 154.5-156 degrees.
