Abstract

A process for preparing a compound of the formula <FORM:1114920/C2/1> wherein R is alkyl (C1- 7), R1 is halogen or alkyl (C1- 7) and R2 is hydrogen, halogen or alkyl (C1- 7) comprises reacting equimolar quantities of the appropriate aniline with an N-acylated anthranilic acid in the presence of a dehydration catalyst which is either potassium hydrogen sulphate, an aliphatic or an aromatic sulphonic acid.
