Procedure

A mixture of N-{2-[5-(chloromethyl)-1,3-thiazol-2-yl]-1H-indol-7-yl}-N-(cyclopropylmethyl)thiophene-2-sulfonamide (100 mg), triethylamine (60 μL), 1-acetylpiperazine (55 mg) and N,N-dimethylformamide (3 ml) was stirred at room temperature for 16 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 obtained residue was subjected to silica gel column chromatography to give the title compound (91 mg, yield 76%) as colorless crystals from a fraction eluted with ethyl acetate. MS 556(M+1).
