Abstract
Procedure to produce fatty N-halogenoacilanilino acids and their ester derivatives, of the general formula: **(See formula)** in which R1 and R2 each represent a lower alkyl group, R3 represents a hydrogen atom, an alkyl, lower alkenyl or lower alkynyl group, R4 represents a lower alkyl group substituted by 1 to 4 halogen atoms and Y represents a lower alkylene group, characterized in that it comprises reacting a fatty anilino acid or its ester derivative represented by the general formula: **(See formula)** wherein R1, R2, R3 and Y are as defined above, with a fatty halogen acid halide represented by the general formula: R4COX in which R4 is as previously defined and X represents halogen, in the presence of an appropriate dehydrohalogenation agent to obtain the N-halogenoacilanilino fatty acid or its ester derivative represented by formula (I).
