반응 단계

To a solution of 5-methyl-1-[5-(trifluoromethyl)pyridin-2-yl]-1H-pyrazole-4-carboxylic acid (40.0 g) described in Reference Example 8 in toluene (147 ml) were added N,N-dimethylformamide (catalyst quantity) and thionyl chloride (52.6 g) at room temperature, and stirred at 80° C. for 4.5 hours. After completion of the reaction, the solvent and excessive thionyl chloride were evaporated, azeotropy was performed with toluene twice, and then dried in vacuo to give the titled compound as a pale yellow solid.
