Procedure
A mixture of {2-[7-(2-methoxy-1-methylethoxy)-5-{[6-(methylsulfonyl)pyridin-3-yl]oxy}-1H-indol-2-yl]-4,5-dihydro-1,3-thiazol-5-yl}acetic acid (250 mg), 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride (140 mg), 1-hydroxybenzotriazole (100 mg) and N,N-dimethylformamide (3 mL) was stirred at room temperature for 30 min. To the mixture was added aqueous ammonium hydroxide solution (25%, 1 mL). 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 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 ethyl acetate-hexane to give the title compound (150 mg, 60%) as pale yellow prisms. MS 519 (MH+). mp 131-132° C.
