実験手順

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 (500 mg), 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride (330 mg), 1-hydroxybenzotriazole (230 mg), dimethylamine (2M solution in tetrahydrofuran, 1.1 mL) and N,N-dimethylformamide (10 mL) 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 residue was purified by silica gel chromatography (ethyl acetate:methanol=100:0 to 95:5, volume ratio) to give pale yellow crystals. The crystals were recrystallized from acetone-methanol to give the title compound (370 mg, 69%) as pale yellow prisms. MS 489 (MH+). mp 206-207° C.
