Procedure

To a solution of N-{2-[5-(aminomethyl)-4,5-dihydro-1,3-thiazol-2-yl]-1H-indol-7-yl}-N-methylthiophene-2-sulfonamide (0.27 g) in N,N-dimethylacetamide (6 mL) was added acetic anhydride (0.10 mL) at 0° C., and the mixture was stirred for 30 min. Water was added to the reaction mixture, and the precipitated solid was collected by filtration, washed with water, and dried. The obtained solid was subjected to silica gel column chromatography to give the title compound (0.20 g, yield 68%) as pale-yellow crystals from a fraction eluted with ethyl acetate-hexane (95:5, volume ratio). melting point 212-213° C.
