YieldReaction ConditionsOperation in experiment
53% for 4 h; Inert atmosphere Sodium methoxide (0.065 g, 1.2 mmol) and 1-(2-chloropyridin-3-yl)ethanone (0.063 gm, 0.4 mmol) were stirred in anhydrous methanol (1.5 mL) in a 7 mL vial under a nitrogen atmosphere for 4 hours. The reaction was cooled to room temperature and 0.5 mL of H2O was added. The mixture was concentratedon a rotary evaporator to remove methanol and the resulting aqueous mixture was partitioned between dichloromethane (20 mL) and water (20 mL). The organic layer was dried over anhydrous sodium sulfate and concentrated on a rotary evaporator to provide the crude product as an orange oil (0.032 g, 53percent yield), which was used without further purification. 1H-NMR (CDCl3) δ 8.33 (dd, J = 4.8 and 2.0 Hz, 1H),8.13 (dd, J = 7.5 and 2.0 Hz, 1H), 7.00 (dd, J = 7.5 and 4.8 Hz, 1H), 4.08 (s,3H), 2.67 (s, 3H). MS (ESI+): m/z (M+H)+ = 152.
