실험 절차

To a mixed solution of methylamine hydrochloride (147 mg), triethylamine (0.31 mL), and N,N-dimethylformamide (25 mL) were added [2-(7-ethyl-5-{[6-(methylsulfonyl)pyridin-3-yl]oxy}-1H-indol-2-yl)-4,5-dihydro-1,3-thiazol-5-yl]acetic acid (500 mg), 1-hydroxybenzotriazole (300 mg), and 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride (420 mg) under ice-cooling, and the mixture was stirred under ice-cooling and then at room temperature for 2 days. Water was added to the reaction solution, and the mixture was extracted with ethyl acetate. The organic layer was washed with aqueous sodium hydrogen carbonate solution and saturated brine, dried over magnesium sulfate, filtered and concentrated under reduced pressure. The obtained residue was subjected to silica gel column chromatography (ethyl acetate:methanol=100:0 to 90:10, volume ratio), and the obtained colorless oil was crystallized from ethyl acetate-hexane to give the title compound (490 mg, yield 95%) as colorless crystals.
