実験手順
To a stirred solution of 3-fluoroaniline (20 g, 0.180 mol) in dichloromethane (100 mL) was added triethylamine (21.816 g, 0.216 mol) and 3-chloropropanoyl chloride (17.18 mL, 0.180 mol) under cooling condition (0° C.) with constant stirring. Reaction mass was allowed to stir at room temperature for 12 h. The reaction mixture was diluted with water (300 mL) and extracted with dichloromethane (4×100 mL). The combined organic layer was washed with saturated aqueous sodium chloride solution, dried over sodium sulphate and concentrated under vacuum to obtain the title compound. 1H NMR (400 MHz, CDCl3) δ 7.51-7.48 (d, J=10.4 Hz, 1H), 7.42 (bs, 1H), 7.29-7.24 (dd, J=14.8 Hz, 8.0 Hz, 1H), 7.15-7.13 (d, J=8.0 Hz, 1H), 6.84-6.81 (t, J=6.8 Hz, 1H), 3.89-3.86 (t, J=6.4 Hz, 2H), 2.83-2.80 (t, J=6.4 Hz, 2H). MS (M+1): 201.9.
