Reaction Steps

To a 0-5° C. cooled suspension of 2-(2-benzo[1,3]dioxol-5-yl-acetylamino)-4,6-difluoro-benzoic acid (0.50 g, 1.49 mmol) in dichloromethane (20 mL) was added 2 M (trimethylsilyl)diazomethane diethyl ether solution (0.82 mL, 1.64 mmol). The mixture was stirred at room temperature for 1 h, then the solvent was evaporated, to provide the title compound (0.52 g, 98% yield).
