Methanesulfonyl chloride → N-(4-bromo-2-fluorobenzyl)methanesulfonamide

Participants

Reaction Steps

To a stirred solution of (4-bromo-2-fluorophenyl)methanamine (5.834 g, 28.592 mmol) in pyridine were added methanesulfonyl chloride (4.2 mL, 54.325 mmol) at 0° C. The reaction mixture was stirred for 1 h, then diluted with dichloromethane. The mixture was washed with water. The organic layer was dried over magnesium sulfate and filtered. The filtrate was removed in vacuo. The crude was purified by column chromatography to give N-(4-bromo-2-fluorobenzyl)methanesulfonamide (7.597 g, 93%).
