Procedure

To a mixture of (2-{7-[[(2-methoxyphenyl)sulfonyl](methyl)amino]-1H-indol-2-yl}-4,5-dihydro-1,3-thiazol-5-yl)acetic acid (150 mg), 2-amino-1,2,4-triazole (36 mg), 1H-1,2,3-benzotriazol-1-ol (67 mg) and N,N-dimethylformamide (8 mL) was added N-[3-(dimethylamino)propyl]-N′-ethylcarbodiimide hydrochloride (94 mg) under ice-cooling, and the mixture was stirred from under ice-cooling to room temperature for 15 hr. The reaction solution was diluted with ethyl acetate, washed with water, aqueous sodium hydrogencarbonate solution and saturated brine, dried over anhydrous magnesium sulfate, and concentrated under reduced pressure. The obtained residue was subjected to silica gel column chromatography (ethyl acetate:methanol=100:0-95:5), and the obtained colorless oil was crystallized from ethyl acetate-hexane to give the title compound (118 mg, yield 69%) as colorless prism crystals. MS: 526 (MH+). melting point 208-209° C.
