Versuchsvorschrift

A mixture of tert-butyl (2E)-3-[4-(benzyloxy)phenyl]acrylate (13.3 g, 42.8 mmol), 10% palladium carbon (1.3 g), ethanol (100 mL) and ethyl acetate (30 mL) was stirred under a hydrogen atmosphere at room temperature for 19 hrs. The catalyst was filtered off and the filtrate was concentrated under reduced pressure to give the title compound (7.5 g, yield 79%) as colorless crystals.
