Participants

Reaction Steps

To a solution of tert-butyl 3-(hydroxymethyl)-5-[(methylsulfonyl)oxy]benzoate (0.284 g, 0.939 mmol) in DCM (5 mL) was added triphenylphosphine (0.370 g, 1.41 mmol) and carbon tetrabromide (0.467 g, 1.41 mmol). After 2 hours, reaction mixture was concentrated in vacuo and purified by flash chromatography (25 g silica, 0-20% EtOAc/hexanes) to give 0.21 g (61%) of tert-butyl 3-(bromomethyl)-5-[(methylsulfonyl)oxy]benzoate. 1H NMR (400 MHz, CDCl3) δ 7.96 (s, 1H), 7.78 (s, 1H), 7.51 (s, 1H), 4.50 (s, 2H), 3.20 (s, 3H), 1.60 (s, 9H).
