Versuchsvorschrift

A mixture of 7-[methyl(2-thienylsulfonyl)amino]-5-(trifluoromethoxy)-1H-indole-2-carboxylic acid (1.60 g), 1H-1,2,3-benzotriazol-1-ol (0.77 g), N-[3-(dimethylamino)propyl]-N′-ethylcarbodiimide hydrochloride (1.09 g) and N,N-dimethylformamide (50 mL) was stirred at room temperature for 15 hr. 28% Aqueous ammonia (320 mg) was added to the reaction mixture, and the mixture was further stirred at room temperature for 2 hr. Water was added to the reaction mixture, and the mixture was extracted with ethyl acetate. The ethyl acetate layer was washed successively with aqueous citric acid solution, saturated aqueous sodium hydrogencarbonate and saturated brine, dried (MgSO4), and concentrated. The residue was washed with hexane to give the title compound (1.25 g, yield 79%) as pale-brown crystals. The crystals were recrystallized from ethyl acetate-hexane to give pale-yellow prism crystals. melting point 228-229° C.
