Methyl 3-bromo-2-(bromomethyl)benzoate (1.28 g) was dissolved in a 11% solution of ammonia in methanol-THF mixed solution (3:2, 25 ml) and the mixture was stirred at room temperature for 16 h. The reaction mixture was concentrated and the residue was washed with saturated brine. Recrystallization from ethyl acetate-hexane gave the title compound (671 mg, 76%) as colorless needle crystals.
