実験手順

A mixture of N-methyl-N-{2-[5-methyl-5-(piperazine-1-ylmethyl)-4,5-dihydro-1,3-thiazol-2-yl]-1H-indol-7-yl}thiophene-2-sulfonamide (0.21 g), acetic anhydride (0.30 ml) and pyridine (6 ml) was stirred at 0° C. for 1 hr, and concentrated. Water was added to the residue, 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 silica gel column chromatography to give the title compound (0.19 g, yield 84%) as a colorless amorphous solid from a fraction eluted with ethyl acetate-methanol (6:1, volume ratio).
