実験手順

EtSO2Cl (21.5 mL, 0.22 mol) was added drop wise to a mixture of 4-fluoro-3-nitroaniline (29.6 g, 0.19 mol) and pyridine (100 mL) at 0° C. The reaction mixture was allowed to warm to room temperature and stirred overnight. The reaction mixture was diluted with EtOAc (1 L). The resulting solution was washed with HCl 2N (4×200 mL), NaHCO3 saturated solution (4×200 mL) and water (4×200 mL). The organic phase was dried over anhydrous Na2SO4 and the solvent was removed to provide the title product as beige solid (46.3 g)
