Abstract

NEW MATERIAL:A 2-methyl-3-amino-propiophenone derivative of formula I: (R is lower alkyl group) and its inorganic acid salt.
EXAMPLE: 4', 2-Dimethyl-3-amino-prpiophenone.
USE: Intermediate for synthesis of medicines e.g. antispasmodics, etc.
PROCESS: A methacylophenone derivative of formula II is reacted with an equimolar or more amount of ammonia in a solvent, e.g. a lower alkanol, etc. at normal pressure and temperature for 5W20 hr to give the 2-methyl-3-amino-propiophenone derivative of formula I and its inorganic acid salt. The starting compound of formula II can be obtained by the Friedel-Crafts reaction of methacrylic acid chloride with a commericially available benzene derivative.
