Reaction Steps

A mixture of 1-benzyl-4-methyl-N-(tetrahydro-2H-pyran-4-yl)-1H-pyrazol-5-amine (1.9 g), activated carbon-supported 20 mass % palladium hydroxide (0.6 g) and formic acid (20 mL) was stirred at room temperature for 16 hr. The insoluble material was filtered off through celite, and the filtrate was concentrated under reduced pressure. The residue was purified by silica gel column chromatography to give the title compound as a colorless solid (0.73 g, 40%).
