Versuchsvorschrift

To a solution of 2-benzylidene-6-methoxy-1-indanone (12.25 g, 48.9 mmol) in ethanol (500 ml) was added 10% hydrous palladium-carbon (1.5 g) and catalytic reduction was carried out in a hydrogen stream at atmospheric temperature and pressure. The palladium-carbon was then filtered off and the filtrate was concentrated under reduced pressure. The residue was purified by silica gel column chromatography (ethyl acetate-hexane=2:8) to provide the title compound (yield 11.26 g, 92%; oil).
