実験手順
To a round bottomed flask equipped with magnetic stirrer was added {4-[2,4-dihydroxyphenyl]cyclohexylidene}acetic acid (50 mg, 0.20 mmol) and ethanol (15 ml). To the stirred solution was added palladium (catalytic amount, 10% on activated carbon) in one portion. The reaction vessel was evacuated and then placed under an atmosphere of hydrogen. This was repeated ten times and then stirred for 17 hr under a hydrogen atmosphere at room temperature. The reaction mixture was filtered through a celite plug, washing with ethanol. The solvent was removed in vacuo to give the title compound (50 mg, 100%) as a pale yellow oil. m/z (ES+) 251 (M+H+); δH(CD3OD) 1.33-1.91 (9H, m), 2.30 (2H, m), 2.81 (1H, m), 6.28 (2H, m), 6.94 (1H, m).
