General description

2-Bromo-4-nitrotoluene is formed as an intermediate during the synthesis of 2-bromo-3-methylbenzoic acid. 2-Bromo-3-methylbenzoic acid can be obtained from 2-bromo-4-nitrotoluene via Von-Richter reaction.

Application

2-Bromo-3-methylbenzoic acid may be used to synthesize N-phenyl-3-methylanthranilic acid via copper-catalyzed amination reaction with aniline.

A chemo- and regioselective copper-catalyzed cross-coupling procedure for amination of 2-bromobenzoic acids is described. The method eliminates the need for acid protection and produces N-aryl and N-alkyl anthranilic acid derivatives in up to 99% yield. N-(1-Pyrene)anthranilic acid has been employed
