実験手順

To a solution of 2-phenylsulfonylamino-5-chloroaniline (90 mg; prepared in Reference Example 12.) and pyridine (0.05 ml) in methylene chloride (5 ml), 4-methoxycarbonylbenzoic acid chloride (70 mg) was added at room temperature in a stream of argon. The mixture was stirred for 6 hours. After the termination of reaction, water was added to the reaction mixture. The mixture was extracted with ethyl acetate. The organic layer was washed, dried over and concentrated under the reduced pressure. The residue was purified by the recrystallization from AcOEt-hexane mixture solvent to give the title compound (112 mg) having the following physical data.
