Versuchsvorschrift

Ethyl [2-(7-[2-methoxy-1-(methoxymethyl)ethoxy]-5-{[6-(methylsulfonyl)pyridin-3-yl]oxy}-1H-indol-2-yl)-4,5-dihydro-1,3-thiazol-5-yl]acetate (390 mg) was dissolved in a mixture of tetrahydrofuran (5 mL) and methanol (5 mL). To the mixture was added 1M aqueous sodium hydroxide solution (2 mL) and the mixture was stirred at room temperature for 1 h. The mixture was concentrated under reduced pressure. The residue was dissolved in water and 1M hydrochloric acid (2 mL) was added to the mixture. The mixture was extracted with ethyl acetate. The organic layer was washed with saturated brine, dried over magnesium sulfate, filtered and concentrated to give the title compound (370 mg, 100%) as a pale orange amorphous solid. MS 550 (MH+).
