To a solution of (E)-3-(3-ethoxy-3-oxoprop-1-en-1-yl)benzoic acid (8.60 g) in ethanol (500 mL) was added 10% palladium-activated carbon (4.10 g) and, under a hydrogen atmosphere, the mixture was stirred at room temperature for 3 hr. The reaction mixture was filtered, and the filtrate was concentrated under reduced pressure to give the title compound (8.70 g) as a white amorphous solid.
