실험 절차

A mixture of ethyl(E)-3-[1-(4-benzyloxybenzyl)-3-(4-fluorophenyl)-1H-pyrazol-4-yl]propenoate (10.0 g), 5% palladium-carbon (20.0 g), ethanol (100 ml) and tetrahydrofuran (100 ml) was stirred for 1 hour under a hydrogen atmosphere. After the palladium-carbon was removed by filtration, the filtrate was concentrated to obtain ethyl 3-[3-(4-fluorophenyl)-1-(4-hydroxybenzyl)-1H-pyrazol-4-yl]propionate (7.15 g, yield 88%) as a colorless oily substance.
