Versuchsvorschrift

A mixture of [2-(7-methoxy-5-{[6-(methylsulfonyl)pyridin-3-yl]oxy}-1H-indol-2-yl)-4,5-dihydro-1,3-thiazol-5-yl]acetic acid (200 mg), 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride (120 mg), 1-hydroxybenzotriazole (90 mg) and N,N-dimethylformamide (3 mL) was stirred at room temperature for 30 min, and then cyclopropylamine (50 mg) was added to the mixture. The whole was stirred at room temperature for 15 h. Water was added to the mixture and the resultant was extracted with ethyl acetate. The organic layer was washed successively with saturated aqueous sodium hydrogen carbonate solution and brine, dried (MgSO4), filtered, and concentrated in vacuo. The residual crystals were washed with ethyl acetate-hexane and collected by filtration to give pale yellow crystals. The crystals were recrystallized from acetone-methanol to give the title compound (150 mg, 68%) as colorless prisms. MS 501 (MH+). mp 248-249° C.
