Reaction Steps
2-Methylpropanoylchloride (79 μl) was added to a mixture of 5-methyl-N-[5-methyl-6-(piperidin-4-yl)pyridin-3-yl]-1-[5-(trifluoromethyl)pyridin-2-yl]-1H-pyrazole-4-carboxamide (222 mg) described in Reference Example 171 and pyridine (2.5 ml), and stirred at 40° C. for five hours. Triethylamine (350 μl), water and ethanol were added to the reaction solution, and the precipitated solid was washed with water to give the titled compound (220 mg) as a white solid.
