Procedure

A solution of 4-[3-(2-benzylphenyl)prop-1-enyl]benzoic acid (6.43 g) in THF (50 ml) containing 10% palladium on carbon (1 g) was stirred under an atmosphere of hydrogen (balloon) for 15 hours. The catalyst was removed by filtration and the residue obtained on removal of the solvent was purified by chromatography on silica. eluting with 5% methanol in dichloromethane, to give 4-[3-(2-benzylphenyl)propyl]benzoic acid, m.p. 135°-6° C.
