反応手順
6-Chloronicotinonitrile (500 mg, 3.61 mmole) and piperazine (930 mg, 10.8 mmole) were dissolved in 20 ml of acetonitrile and heated at 60° C. under N2 for 5 hours. The mixture was cooled to room temperature, diluted with water and extracted with dichloromethane (5×). The combined organics were dried over sodium sulfate, filtered, and concentrated to provide the title compound. 1H NMR (300 MHz, CDCl3) δ 8.40 (d, J=1.70 Hz, 1H) 7.60 (dd, J=8.81, 2.37 Hz, 1H) 6.59 (d, J=8.48 Hz, 1H) 3.57-3.75 (m, 4H) 2.91-3.05 (m, 4H); MS (M+H)+=189.
