実験手順

To a solution of N-{5-hydroxy-2-[5-(thiomorpholinomethyl)-4,5-dihydro-1,3-thiazol-2-yl]-1H-indol-7-yl}-N-methylpyridine-2-sulfonamide (800 mg) in N,N-dimethylformamide (10 mL) were added potassium carbonate (264 mg) and ethyl bromoacetate (0.18 mL), and the mixture was stirred at 50° C. for 6 hr. The mixture was diluted with ethyl acetate, washed with water and saturated brine, dried over anhydrous magnesium sulfate, and concentrated under reduced pressure. The residue was purified by silica gel column chromatography (hexane:ethyl acetate=85:15-0:1) to give the title compound (724 mg, yield 76%) as a pale-yellow powder.
