Water → 4-Sulfamoylanilino-alpha-[4-(2-furyl)phenyl]acetnitrile

Participants

Reaction Steps

To a suspension of 4-sulfamoyl-N-[4-(2-furyl)benzylidene]aniline (0.37 g, 1.13 mmol) in anhydrous THF (5 mL) at 0° C. was added trimethylsilyl cyanide (0.135 g, 1.36 mmol), zinc chloride (1.36 mL, 1.0 M solution in ether, 1.36 mmol). The temperature of the reaction mixture was then allowed to return to room temperature, and the mixture was stirred overnight. The reaction mixture was poured into water and the whole was extracted with ethyl acetate (20 mL×2). The organic layer was washed with brine, dried over Na2SO4, and concentrated to give the subtitle compound (0.288 g). 1H-NMR (DMSO-d6) δ: 7.84-7.78 (m, 3H), 7.65-7.60 (m, 4H), 7.39 (d, J=9 Hz, 1H), 7.04-7.01 (m, 3H), 6.91 (d, J=9 Hz, 2H), 6.62 (dd, J=3, 2 Hz, 1H), 6.16 (d, J=9 Hz, 1H). MS (EI) m/z 353 (M+)
