Versuchsvorschrift
A mixture of 55.2 g. of 3-phenyl phthalide (0.263 mole), 600 ml. ethanol and 5.9 g. of 10% Pd/C is hydrogenated at room temperature and 50 psi until 1 equivalent of H2 is absorbed. The catalyst is removed by filtration and the solvent removed in vacuo and the residue triturated in petroleum ether to give α-phenyl-o-toluic acid; m.p. 101°-104° C.
