실험 절차

To a mixture of 2,4-dichloro-6-methoxy-1,3,5-triazine (370 mg) and tetrahydrofuran (10 mL), a mixture of 2-(isopropylsulfonyl)aniline (400 mg), N-ethyl-N-isopropylpropane-2-amine (0.72 mL) and tetrahydrofuran (5 mL) was added and stirred overnight at room temperature and further stirred at 70° C. for 7 hours. The reaction mixture was cooled on ice and diluted with water (60 mL). The precipitated solid was collected by filtration, purified by silica gel column chromatography (eluent; chloroform) and then washed with hexane to give 4-chloro-N-[2-(isopropylsulfonyl)phenyl]-6-methoxy-1,3,5-triazine-2-amine (200 mg) as a white solid.
