실험 절차

To a solution of N-{2-[5-(2-hydroxyethyl)-5-methyl-4,5-dihydro-1,3-thiazol-2-yl]-1H-indol-7-yl}-N-methylthiophene-2-sulfonamide (0.75 g) and triethylamine (0.50 mL) in tetrahydrofuran (10 mL) was slowly added methanesulfonyl chloride (0.20 mL) at 0° C., and the mixture was stirred at room temperature for 1 hr. Water was added to the reaction mixture, and the mixture was extracted with ethyl acetate. The ethyl acetate layer was washed with saturated brine, dried (MgSO4), and concentrated. The residue was subjected to silica gel column chromatography to give the title compound (0.56 g, yield 65%) as colorless crystals from a fraction eluted with ethyl acetate-hexane (3:1, volume ratio). melting point 149-150° C.
