To a solution of 1-phenylcyclopropanecarbonitrile (0.5 g, 3.5 mmol) in 5 mL of chloroform was added 0.5 mL of ClSO3H at 0° C. After stirring at rt stirred overnight, the reaction mixture was poured into ice-water (50 mL) and the product was extracted with CHCl3 (75 mL). The extracts were washed with water (50 mL) and brine (50 mL), dried over anhydrous MgSO4, and concentrated to give the title compound. 1H NMR (500 MHz, CD3OD): δ 8.08 (2H, d), 7.77 (2H, d), 1.60 (2H, t), 1.21 (2H, t).
