氟甲磺酰氯

反应条件: temp:100.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: Commercially available fluoromethanesulfonyl chloride (975 mg, 7.36 mmol) is added dropwise to a solution of sodium sulfite (1.85 g, 14.7 mmol) and sodium bicarbonate (1.24 g, 14.7 mmol) in water (2 mL). The reaction mixture is heated in a microwave reactor to 100° C. for 20 minutes. After cooling to room temperature commercially available 5-bromo-2-(chloromethyl)pyridine (894 mg, 3.68 mmol) in ethanol (2 mL) is added. The mixture is heated in a microwave reactor to 100° C. for 20 minutes. The reaction mixture is cooled to 0° C. and the solid filtered off and discarded. The filtrates are diluted with saturated sodium carbonate (10 mL), extracted with tertiarybutyl methyl ether (50 mL). The organic layer is separated, dried over sodium sulfate, filtered and the solvent removed under reduced pressure to give the title compound (150 mg): m/z 268.9 (M+H)+. is added The mixture is heated in a microwave reactor to 100° C. for 20 minutes The reaction mixture is cooled to 0° C. the solid filtered off The filtrates are diluted with saturated sodium carbonate (10 mL) extracted with tertiarybutyl methyl ether (50 mL) The organic layer is separated dried over sodium sulfate filtered the solvent removed under reduced pressure
