Versuchsvorschrift

To a solution of methyl 3-cyclohexyl-2-{2-[2-(tetrahydropyran-2-yloxy)ethylsulfanyl]phenyl}-1H-indole-6-carboxylate (1.38 g, 2.81 mmol) in tetrahydrofuran (4 ml) and methanol (4 ml) was added 6N hydrochloric acid (4 ml), and the mixture was stirred at room temperature for 30 min. Water was added to the reaction mixture and the mixture was extracted with ethyl acetate. The organic layer was successively washed with water, saturated aqueous sodium hydrogen carbonate solution and saturated brine and dried over anhydrous sodium sulfate. After filtration, the solvent was evaporated under reduced pressure, and the residue was purified by silica gel chromatography (hexane:ethyl acetate=2:1-1:1) to give methyl 3-cyclohexyl-2-[2-(2-hydroxyethylsulfanyl)phenyl]-1H-indole-6-carboxylate (1.00 g, yield 87.5%).
