Reaction Steps
In the practice of this invention, the 2-nitro-1-phenyl-1-propanol is dissolved in a lower alkyl alcohol, preferably isopropyl alcohol. The mixture is placed in a vessel suitable for high pressure reactions and equipped with agitation means, e.g. a rocking bomb or a stirred bomb. Acetic acid is added to the solution to produce the acetate salt of 2-amino-1-phenyl-1-propanol during the reduction reaction.
