Abstract

1367435 γ-Amino-#-hydroxybutanoic acid amide ONO PHARMACEUTICAL CO Ltd 11 May 1973 [11 May 1972] 22701/73 Heading C2C The novel title compound is prepared by action of ammonia on γ-chloro-#-hydroxy butanoic acid amide or on γ-chloro-#-butyrolactone. A process of preparation of γ-amino-#- hydroxybutanoic acid by hydrolysis of the above novel compound is disclosed. γ-chloro-#-hydroxybutanoic acid amide is prepared by aqueous alkaline hydrogen peroxide on γ-chloro-#-hydroxy-butyronitrile. The lactone is prepared by action of halogen on vinylacetic acid in aqueous sodium bicarbonate solution.
