実験手順

A mixture of ethyl 2-phenylcyclohexa-1,3-dienecarboxylate(90 mg, 0.395 mmol) and 5%Pd/C(50 mg) in acetic acid(1.5 ml) and water(1.5 ml) was refluxed for 2 hr. The reaction mixture was filtrated and the solvent was evaporated under reduced pressure. Toluene was added to the residue and it was dried over MgSO4. After removal of the solvent, the residue was purified by column chromatography on silica gel with n-hexane-AcOEt to afford 71 mg of ethyl 2-phenylbenzoate(y=80.0%) as a pale yellow oil. 1H-NMR(ppm, 300 MHz, CDCl3) δ 7.82(1H, dd, J=1.4 and 7.7 Hz), 7.10-7.60(8H), 4.08(2H, d, J=7.0 Hz), 0.98(3H, t, J=7.0 Hz)
