Procedure
In an analogous manner, by the reaction of ethyl 4-(2-aminoethyl)-phenylacetate with 5-chloro-2-methoxybenzoyl chloride, there is obtained, via ethyl 4-[2-(5-chloro-2-methoxybenzamido)-ethyl]-phenylacetate (oil), 4-[2-(5-chloro-2-methoxybenzamido)-ethyl]-phenylacetic acid; m.p. 127°-128° C., after recrystallization from 75% acetic acid.
