실험 절차

A mixture of (2-{7-[methyl(pyridin-2-ylsulfonyl)amino]-1H-indol-2-yl}-4,5-dihydro-1,3-thiazol-5-yl)methyl methanesulfonate (1.0 g), 1H-1,2,4-triazole (290 mg), potassium carbonate (580 mg) and N,N-dimethylformamide (10 mL) was stirred at 60° C. for 15 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 basic silica gel column chromatography, and eluted with hexane-ethyl acetate-methanol (50:50:0-0:100:0-0:95:5, volume ratio) to give N-methyl-N-{2-[5-(1H-1,2,4-triazol-1-ylmethyl)-4,5-dihydro-1,3-thiazol-2-yl]-1H-indol-7-yl}pyridine-2-sulfonamide (560 mg, yield 59%) as a pale-yellow amorphous solid.
