Reaction Steps

4-Bromo-2-bromomethyl-benzoic acid methyl ester (3.70 g) was suspended in 2M NH3 in MeOH (36 mL) and concentrated ammonium hydroxide (12 mL) for eighteen hours. The solid product was filtered to provide the title compound as a colourless solid (2.30 g, 90%). 1H NMR (300M, CDCl3): δ 7.68 (m, 3H), 4.44 (s, 2H).
