Participants

Reaction Steps

To a mixture of (2-{7-[methyl(2-thienylsulfonyl)amino]-1H-indol-2-yl}-1,3-thiazol-5-yl)acetic acid (0.38 g), morpholine (0.16 g), 1H-1,2,3-benzotriazol-1-ol (0.18 g) and N,N-dimethylformamide (10 mL) was added N-[3-(dimethylamino)propyl]-N′-ethylcarbodiimide-hydrochloride (0.26 g) at 0° C., and the mixture was stirred at room temperature for 4 hr. Water was added to the reaction mixture, and the obtained crystals were filtrated, washed with water and dried. A solution of the obtained crystals in tetrahydrofuran was treated with activated carbon and concentrated to give the title compound (0.37 g, yield 83%) as colorless crystals. The crystals were recrystallized from ethyl acetate. melting point 199-200° C.
