실험 절차

3-Oxetanone (121 mg) and sodium triacetoxyborohydride (143 mg) were added at room temperature to a solution of 5-methyl-N-[5-methyl-6-(piperidin-4-yl)pyridin-3-yl]-1-[5-(trifluoromethyl)pyridin-2-yl]-1H-pyrazole-4-carboxamide (250 mg) described in Reference Example 171 in dichloromethane (24 ml), and stirred at the same temperature for five hours. After completion of the reaction, water was added and extracted with ethyl acetate. The organic solution was dried over anhydrous sodium sulfate and concentrated. 1N Aqueous solution of sodium hydroxide (20 ml) was added to the resulting residue, solid was collected by filtration purified with silica gel column chromatography (chloroform/methanol) to give the titled compound (100 mg) as a white solid.
