To a solution of 3-(2H-tetrazol-5-yl)phenol (250.8 mg, 1.547 mmol) in MeCN (10 mL) at rt was added Et3N (0.237 mL, 1.701 mmol) followed by methyl bromoacetate (260 mg, 1.701 mmol). The reaction was stirred at rt for 16 h. Volatiles were removed. Chromatography over silica eluting with 30-60% EtOAc/hexanes afforded the title compound as a white solid. 1H NMR (500 MHz, CDC13): δ 7.75 (d, 1H, J=7.5 Hz), 7.69 (s, 1H), 7.39 (t, 1H, J=8.0 Hz), 7.01 (dd, 1H, J=8.0, 2.3 Hz), 5.53 (bs, 1H), 5.50 (s, 2H), 3.86 (s, 3H).
