실험 절차

To N-[6-(1-tert-butyloxycarbonylpiperidin-4-yl)-5-methylpyridin-3-yl]-5-methyl-1-[5-(trifluoromethyl)pyridin-2-yl]-1H-pyrazole-4-carboxamide (7.0 g) were added dichloromethane (128 ml) and trifluoroacetic acid (26 ml), stirred at room temperature for 2 hours, and then to the reaction solution was added 4 N aqueous solution of sodium hydroxide under ice-cooling. The precipitated solid was washed with n-hexane and water, the obtained solid was dissolved in chloroform, water was added thereto, extracted with chloroform and ethyl acetate, dried over anhydrous sodium sulfate, and then the solvent was evaporated in vacuo. The precipitated solid was washed with ethyl acetate to give the titled compound (5.39 g) as a white solid.
