A novel method for the synthesis of anthranilate esters is described. The esterification reaction of nitro-substituted anthranilic acids was carried out under microwave irradiation. A range of solvents and other reaction parameters were investigated to provide the most environmentally friendly reaction conditions. The feasibility of scale-up was demonstrated, allowing a simple and inexpensive production of anthranilate esters.
