Procedure

To a solution of N-{2-[5-(chloromethyl)-1,3-thiazol-2-yl]-1H-indol-7-yl}thiophene-2-sulfonamide (0.250 g) in N,N-dimethylformamide (6 ml) were added N,N-dimethyl-2-piperazin-1-ylacetamide (0.208 g) and triethylamine (0.17 ml), and the mixture was stirred at room temperature for 15 hr. Water was added to the reaction solution, and the mixture was extracted with ethyl acetate. The extract was washed with saturated brine, dried over anhydrous magnesium sulfate, and concentrated under reduced pressure. The residue was purified by silica gel column chromatography (methanol), and recrystallized from ethyl acetate-hexane to give the title compound (0.230 g, yield 69%) as colorless crystals.
