Procedure

To a mixture of 2-{7-[methyl(pyridin-2-ylsulfonyl)amino]-1H-indol-2-yl}-4,5-dihydro-1,3-thiazol-5-yl)acetic acid (72 mg) obtained in Example 336, 1H-1,2,3-benzotriazol-1-ol-ammonia complex (40 mg) and N,N-dimethylformamide (3 mL) was added N-[3-(dimethylamino)propyl]-N′-ethylcarbodiimide hydrochloride (50 mg) under ice-cooling, and the mixture was stirred from under ice-cooling to room temperature for 18 hours. 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 crystallized from ethyl acetate-hexane to give the title compound (57 mg, yield: 79%) as pale-yellow prism crystals. MS: 430 (MH+). melting point 148-149° C.
