- Abstract
The reactions of 4-aminobenzoic and 4-aminophenylacetic acids amides with maleic anhydride yielded the corresponding maleic acid monoamides, the cyclization of which gave 4-(2,5-dihydro-2,5-dioxo-1H-pyrrol-1-yl)benzoic and 4-(2,5-dihydro-2,5-dioxo-1H-pyrrol-1-yl)phenylethanoic acids amides. Their reactions with secondary amines afforded the corresponding 4-(3-dialkylamino-2,5-dioxo-2,3,4,5-tetrahydro-1H-pyrrol-1-yl)benzoic and 4-(3-dialkylamino-2,5-dioxo-2,3,4,5-tetrahydro-1H-pyrrol-1-yl)phenylethanoic acids amides.
