Nicotinoyl chloride → HCID 6461622, compound

Participants

Reaction Steps

4-Fluoro-N′-hydroxybenzimidamide (0.154 g, 1 mmol) was dissolved in pyridine (10 mL) and nicotinoyl chloride (Aldrich, 0.141 g, 1 mmol) was added. The reaction mixture was heated to reflux for 3 hours and then cooled to room temperature. The cooled reaction mixture was quenched with water (25 mL) and filtered. The solid was further purified with flash column chromatography (5% methanol/dichloromethane) to give the titled product. 1H NMR (300 MHz, DMSO-d6) δ 7.47 (t, J=6.8 Hz, 2H), 7.74-7.70 (m, 1H), 8.20-8.15 (m, 2H), 8.58-8.54 (m, 1H), 8.91-8.89 (dd, J=1.7, 1.7 Hz, 1H), 9.35 (d, J=1.4 Hz, 1H) ppm; MS (DCI/NH3) m/z 242 (M+H)+.
