Pellon, Rolando F.,Carrasco, Ramon,Marquez, Tania,Mamposo, Taimirys
, p. 5107 - 5110 (1997)
It is known that N-phenylanthranilic acids can be synthesized by Ullmann-Goldberg condensation in different conditions. This paper reports some parameters which influence the condensation and reports a general procedure for this reaction using N,N-Dimethylformamide as solvent.

N-Phenylanthranilic acid derivatives were synthesised using the Ullmann condensation of 2-chlorobenzoic acid with aniline derivatives under microwave irradiation in aqueous media. The method offers better yields in shorter reaction times compared to classical heating approaches using water as solvent.
