Analogously to Example 1, by using equivalent quantities, reacting N-(p-chlorobenzoyl)-2-(2,6-dimethylanilino)acetic acid and ethyl L-prolinate and suitable processing produces ethyl N-[N-(p-chlorobenzoyl)-2-(2,6-dimethylanilino)acetyl]-L-prolinate (oil), saponification of which and processing of the reaction product yields N-[N-(p-chlorobenzoyl)-2-(2,6-dimethylanilino)acetyl]-L-proline (M.P. 199°).
