Abstract

A series of N-arylanthranilic acid derivatives were synthesised by amination of 2-chloro-5- nitrobenzoic acid with various arylamine in superheated water with potassium carbonate as base. Good yields were achieved within 2–3 h at 150–190° C. The results indicated that this metal catalyst-free method is a simple, environmentally-friendly and efficient synthesis of N- phenylanthranilic acid derivatives. Furthermore, it will work with an alkylamine and phenol.
