To a stirred solution of (2-fluoro-4-nitrophenyl)methanamine (194 mg, 1.140 mmol) in pyridine, cooled to 0° C., were added methanesulfonyl chloride (248 mg, 2.166 mmol). The resulting reaction mixture was stirred for 1 h at room temperature. The mixture was dissolved in dichloromethane and washed with 1N HCl. The organic layer was dried over magnesium sulfate and filtered. The filtrate removed in vacuo. The crude was purified by column chromatography. N-(2-Fluoro-4-nitrobenzyl)methanesulfonamide (250 mg) was obtained as 88% yield.
