Versuchsvorschrift
Analogously to Example 1, by using equivalent quantities, reacting N-(p-chlorobenzoyl)-2-(2,6-dimethylanilino)acetic acid and ethyl 4-(2,6-dimethylanilino)butyrate and suitable processing produces ethyl N-[N-(p-chlorobenzoyl)-2-(2,6-dimethylanilino)acetyl]-4-(2,6-dimethylanilino)butyrate (M.P. 150° to 151°), saponification of which and processing of the reaction product yields N-[N-(p-chlorobenzoyl)-2-(2,6-dimethylanilino)acetyl]-4-(2,6-dimethylanilino) butyric acid (M.P. 214° to 216°).
