Versuchsvorschrift

35 mg of (6-methoxy-2-cyclopentylbenzo[b]thien-3-yl)[4-[2-(dimethylamino)ethoxy]phenyl]methanone is dissolved in 5 mL of dichloromethane, 65 mg of aluminum chloride and 0.03 mL of ethanethiol are added, and this mixture is agitated for two hours at room temperature. 0.3 mL of THF, 0.075 mL of 20% hydrochloric acid, and 0.3 mL of water are added to the reaction mixture, after which a saturated aqueous solution of sodium hydrogencarbonate is added to render the solution alkaline, and the organic layer is extracted with ethyl acetate and dried with anhydrous magnesium sulfate. The solvent is distilled off, and the crude product thus obtained is refined by TLC (developing solvent was chloroform:methanol=19:1), which gives 21 mg of (6-hydroxy-2-cyclopentylbenzo[b]thien-3-yl)[4-[2-(dimethylamino)ethoxy]phenyl]methanone.
