実験手順
To a solution of ethanesulfonyl chloride (0.368 ml, 3.89 mmol) in DCM (1 ml) and pyridine (1 ml) was added 2-fluoroaniline (0.360 ml, 3.89 mmol) at rt and the reaction was stirred at 50° C. for 5 hours. The reaction was then stirred at rt overnight. The reaction was diluted with EtOAc and washed with H2O and sat. NaCl solution. The organic layer was dried over Na2SO4 and concentrated. Purification of the residue by flash chromatography on silica gel (eluent: 0% to 35% EtOAc/hexane) provided the title compound as a white solid.
