反応手順
A solution of 2M dimethylamine in THF (5.9 mL, 12 mmol) was diluted with DCM (25 mL) and cooled to 0° C. DIPEA (2.8 mL) was added, followed by and 3-chloro-4-fluorobenzenesulfonyl chloride (2.5 g, 11 mmol) in DCM (25 mL). The resulting mixture was allowed to warm to rt and stirred for 3 hours. Water (5 mL) and 1M hydrochloric acid (16 mL) was added. The organic phase was separated and evaporated under reduced pressure to afford the title compound (2.4 g, 94%).
