Procedure
Under a stream of argon gas, 0.11 g of 5-(4-benzyloxyphenylacetylamino)-3-(4-fluorophenyl)-1-methyl-4-(4-pyridyl)pyrazole, 22.9 mg of palladium hydroxide-carbon, and 8 ml of cyclohexene were added to 15 ml of ethanol followed by heating under reflux for 23 hours. After the reaction mixture was cooled to room temperature, the catalyst was filtered off and the solvent was distilled off under reduced pressure. The resulting residue was purified by column chromatography using 30 g of silica gel [with an elution solvent comprising chloroform-methanol (100:0-40:1)]. Thus, 61.3 mg (69% yield) of the title compound was obtained as white crystals.
