Procedure

To a suspension of 6-chloronicotinoyl chloride (10.5 g, 59.7 mmole) in dry dichloromethane (100 mL) was added 4-fluoroaniline (5.6 mL, 59.7 mmole), followed by the dropwise addition of N,N-diisopropylethylamine (21 mL, 119 mmol). After stirring for 90 min at room temperature, the mixture was diluted with ethyl acetate (20 mL) and washed with water. The combined organic extracts were dried over anhydrous sodium sulfate, filtered, and concentrated in vacuo. Purification by recrystallization using ethyl acetate/hexanes gave 13.8 g (92%) of a white solid. 1H NMR (300 MHz, CDCl3) δ7.09–7.12 (m, 2H), 7.47–7.50 (m, 1H), 7.56–60 (m, 2 H), 7.7 (bs, 1H), 8.15–8.18 (m, 1H), 8.84 (m, 1H); MS (EI) m/z 251.13 (M+H)+.
