4-(3-Oxo-3-phenyl-propenyl)-benzoic acid (7.64 g, 30 mmol) is combined with Raney nickel (2 g) in ethanol (140 mL). The mixture is hydrogenated at room temperature and 50 psi for 1.5 h. The reaction is filtered evaporated in vacuo. The resulting residue is recrystallized from ethyl acetate to obtain 4.57 g (59%) of the titled compound. m.p.=145-147° C.; Anal. Calcd for C16H14O3: C, 75.58; H, 5.55. Found: C, 75.60; H, 5.32.
