Procedure

Isopropylsulfonyl chloride (72 μl) was added to a suspension 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 potassium carbonate (138 mg) in N,N-dimethylformamide (1.7 ml) and stirred at room temperature for an hour. Then, isopropylsulfonyl chloride (36 μl) was added and stirred at room temperature for two hours. Triethylamine (350 μl) and water were added and the precipitated solid was washed with ethanol and water. The resulting solid was purified with silica gel chromatography (chloroform/methanol) to give the titled compound (103 mg) as a white solid.
