摘要

A series of novel N-(p-benzamido)-2-pyrrolidone-4-carboxylic acid compounds have been prepared by condensing the corresponding p-aminobenzamides with itaconic acid. These pyrrolidone compounds are useful in therapy as anti-ulcer agents. N-[N'-(n-Decyl)-4'-benzamido]-2-pyrrolidone-4-carboxylic acid represents a preferred embodiment.
