Reaction Steps

Under hydrogen atmosphere, a mixed solution of 1-(5-cyclopropyl-2-chloropyridin-3-yl)-5-methyl-1H-pyrazole-4-carboxylic acid (400 mg) in Reference Example 121 and palladium-activated carbon ethylenediamine complex (100 mg) in ethanol (50 ml) was stirred at room temperature. After completion of the reaction, the solution was filtered through Celite, and the solvent was evaporated in vacuo. The obtained residue was purified with silica gel chromatography (chloroform/methanol) to give the titled compound (184 mg) as a white solid.
