Versuchsvorschrift

3-(3,4,5-Trimethoxyphenyl) -2-propen-1-ol (120 mg) was dissolved in ethanol, and to the solution 10% palladium on carbon (60 mg) was added, and the mixture was stirred at room temperature for 3 hours under a hydrogen atmosphere. The reaction mixture was filtered through celite, the filtrate was then concentrated under reduced pressure and extracted with chloroform. The resultant organic layer was washed with saturated brine, dried over anhydrous sodium sulfate and concentrated under reduced pressure. The residue was purified by column chromatography on silica gel (chloroform:methanol=14:1) to obtain the title compound.
