2-Nitro-6-methylbenzoic acid (0.91 g) and benzylamine (0.53 g) were dissolved in NMP (5 mL) and DIPEA (3 mL). HATU (1.9 g) was added and the mixture was stirred for 1 hour. The reaction mixture was diluted with ethyl acetate and washed with 1N hydrochloric acid, saturated aqueous sodium bicarbonate and then brine. The organic solution was dried with magnesium sulfate, filtered and the solvent was removed under vacuum to give a light brown oil (1.01 g) that crystallized on standing.
