Versuchsvorschrift

To a solution of ethyl[2-(7-ethyl-5-{[6-(methylsulfonyl)pyridin-3-yl]oxy}-1H-indol-2-yl)-4,5-dihydro-1,3-thiazol-5-yl]acetate (3.0 g), methanol (15 mL), and tetrahydrofuran (30 mL) was added an aqueous solution (10 mL) of potassium hydroxide (1.1 g), and the mixture was stirred at room temperature for 15 hr. The reaction solution was concentrated, acidified with aqueous citric acid solution, and the mixture was extracted with ethyl acetate. The organic layer was washed with saturated brine, dried over magnesium sulfate, filtered and concentrated under reduced pressure. The obtained pale-yellow crystals were washed with ethyl acetate-hexane to give the title compound (2.5 g, yield 88%) as pale-yellow crystals.
