ABSTRCT OF THE DISCLOSURE: 3-Amino-4-lower carboalkoxy-benzoic acid-4'-phenoxy-anilides which may be halogenated in the phenoxy nucleus are obtained by reacting the corre- sponding 4-carboalkoxy-benzoyl chloride having in 3-position a group cap- able of yielding the amino group with a 4-amino-diphenyl ether which may be halogenated in the phenyl nucleus which is not substituted by the amino group, and setting free the amino group from the group capable of yielding it.
