A mixture of 3-(4-t-butyloxycarbonylphenyl)acrylic acid ethyl ester (11.52 g) and 5% palladium-charcoal in ethanol (115 ml) was stirred under hydrogen atmosphere at room temperature. The catalyst was removed by filtration and washed with ethanol. The combined solution was evaporated to give 3-(4-tert-butyloxycarbonylphenyl)propionic acid ethyl ester.
