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 (250 mg), ethyl 1H-imidazole-2-carboxylate (146 mg), potassium carbonate (144 mg) and N,N-dimethylformamide (5 mL) was stirred at 60° C. for 4.5 hr. Water was added to the reaction mixture, and the mixture was extracted with ethyl acetate. The organic layer was washed successively with water and saturated brine, dried over magnesium sulfate, and filtrated, and the filtrate was concentrated under reduced pressure. The residue was purified by silica gel column chromatography (ethyl acetate:hexane=15:85-100:0) to give the title compound (227 mg, yield 83%) as a orange oil.
