Reaction Steps
A mixture of 1-benzyl-N-(tetrahydro-2H-pyran-4-yl)-1H-pyrazol-5-amine (3.00 g), palladium-carbon (10 wt %, 2.33 g) and ethanol (100 mL) was stirred under a hydrogen atmosphere at 50° C. and 5 atm for 9 hr. The insoluble material was filtered off, and the solvent was evaporated under reduced pressure. The residue was purified by silica gel column chromatography to give the title compound as a colorless solid (1.70 g, 87%).
