Abstract

1,194,578. 4 - Methyloxazole - 5 - carboxylic alkyl esters. BADISCHE ANILIN- & SODAFABRIK A.G. 10 Nov., 1967 [12 Nov., 1966], No. 51278/67. Heading C2C. 4 - Methyloxazole - 5 - carboxylic acid alkyl esters are produced by reacting α-chloroacetoacetic acid alkyl esters with formamide, preferably at 80-180‹ C. Examples are given of the preparation of the required ethyl and n-butylesters from the corresponding esters of α-chloroacetoacetic acid. Other esters mentioned as starting materials are the methyl, propyl, amyl and isobutyl esters.
