Reaction Steps

LiAlH4 (0.68 g) in diethyl ether (30 mL) was treated with 4-bromo-3-methylbenzonitrile (15 mmol) and refluxed for 2 hours. The mixture was cooled to 0° C. and treated in succession with water (0.7 mL), 20% NaOH (0.5 mL), and water (2.5 mL). The mixture was filtered through a celite pad and the filter cake was washed several times with diethyl ether. The filtrate was dried over Na2SO4, filtered, and the filtrate was concentrated under reduced pressure to provide the title compound. MS (ESI+) m/z 194 (M+H)+; MS (ESI−) m/z 192 (M−H)−; 1H NMR (DMSO, 300 MHz) δ 3.97 (s, 2H), 7.30 (m, 1H), 7.46 m, 2H).
