Versuchsvorschrift

A solution of compound 80-2 (2.04 g) and p-toluenesulfonic acid monohydrate (10.0 mg) in methanol (80 ml) was stirred at room temperature for 20 hr. Saturated aqueous sodium hydrogen carbonate was added to the reaction mixture, and methanol was evaporated under reduced pressure. Water was added to the obtained mixture, and the mixture was extracted with ethyl acetate. The organic layer was washed with saturated brine and dried over anhydrous magnesium sulfate, and the solvent was concentrated under reduced pressure to give the object product (1.48 g) as a brown oil.
