Participants

Reaction Conditions

Reaction Steps

2-Aminobenzonitrile (5.0 g, 42.3 mmol) was taken into dichloromethane (60 mL). NBS (7.54 g, 42.3 mmol) was added and stirred at 0° C. for 3 h. The reaction mixture was diluted with dichloromethane and washed with brine, dried over MgSO4. The crude product was purified by column chromatography (hexane/ethyl acetate=10/1) to afford the titled compound (7.20 g, 87%). 1H NMR (400 MHz, DMSO-d6): δ 6.22 (s, 2H), 6.75 (d, J=9.2 Hz, 1H), 7.42 (dd, J=8.8 Hz, 2.4 Hz, 1H), 7.58 (s, 1H).
