实验步骤: A solution of 4-(bromomethyl)benzonitrile (500 mg, 2.55 mmol) in 90% sulphuric acid (8 ml) was heated at 100° C. for 1 h. The solution was carefully poured onto ice water (50 ml) and a precipitate formed. The solid was filtered, washed with water and diethyl ether and dried in vacuo to afford the title compound as a white solid (353 mg, 65%). The solution was carefully poured onto ice water (50 ml) a precipitate formed The solid was filtered washed with water and diethyl ether dried in vacuo
