实验步骤: To a solution of tert-butyl 4-hydrazinopiperidine-1-carboxylate (646 mg) and ethanol (15 mL) was added phenyl malonaldehyde (444 mg), followed by stirring at 75° C. for about 1.5 days. The reaction liquid was concentrated under reduced pressure, and the residue was purified by silica gel column chromatography (hexane/chloroform-50/50 to 0/100) to obtain tert-butyl 4-(4-phenyl-1H-pyrazol-1-yl)piperidine-1-carboxylate (226 mg). The reaction liquid was concentrated under reduced pressure the residue was purified by silica gel column chromatography (hexane/chloroform-50/50 to 0/100)
