Abstract

1330237 Cleavage of carboxylic amides TOHO BESLON KK 3 Dec 1971 [30 Dec 1970 18 Sept 1971 (2)] 56173/71 Heading C2C Amides of the formula R 1 CONHR 2 , in which R 1 is a saturated or unsaturated hydrocarbon radical of 2 or 3 carbon atoms or the methoxy derivative of such a radical, and R 2 is a tertiary alkyl radical, are cleaved to produce R 1 COOH and R 2 NH 2 by heating in an inert gas atmosphere with an alkali (e.g. NaOH or KOH) in the presence of methanol to above 140‹ C., preferably at 150-250‹ C. Examples obtain tert.- butyl amine. The acids R 1 COOH may be esterified. Acids isolated in examples are acrylic acid (esterified to give methyl acrylate) and methoxypropionic acid. Methyl acrylate is also obtained by refluxing methoxypropionic acid with H 2 SO 4 .
