反应详情

To a solution of 4-fluorobenzenesulfonyl chloride (2 g, 10.3 mmol) at room temperature was stirred with pyridine (2.49 mL, 30.8 mmol) and 4-fluoroaniline (1.95 mL, 20.6 mmol) for 2 hrs. The reaction was quenched with 1 M HCl aqueous and then extracted with DCM, filtered through a phase separator and purified by silica gel column chromatography (0-100% DCM in cyclohexane) to give 4-fluoro-N-(4-fluoro-phenyl)-benzenesulfonamide (2.15 g, 78%). LCMS (m/z, Method A) ES+ 270 [M+1]+.
