Reaction Steps

2-Amino-3-methylbenzoic acid (10 g, 66 mmol) was dissolved in 70 mL of N,N-dimethyl-formamide (DMF) and treated with N-iodosuccinimide (16.4 g, 73 mmol). The mixture was heated at 60° C. for 17 hours and allowed to cool to 25° C. The mixture was diluted with water (150 mL and filtered. The air-dried solid was dissolved in ethyl acetate (200 mL) and dried over magnesium sulfate. Evaporation of the solvent provided the title compound of Step A (7.95 g). 1H NMR (CDCl3): δ 7.87 (1H), 7.44 (1H), 2.09 (3H).
