2-(4-Vinylphenyl)-2-methylpropanoic acid (58 g) was dissolved in ethanol, and then stirred for 3 hrs under atmospheric hydrogen pressure in the presence of 10% palladium carbon (5.8 g). The catalyst was removed by filtration, and the filtrate was concentrated to obtain a crude product, which was then suspended and washed with hexane to give the title compound (56.5 g, 94.8%).
