実験手順

To a solution of 5-amino-2-bromo-6-picoline (701 mg) and triethylamine (1.57 ml) in tetrahydrofuran (20 ml) was added 5-methyl-1-[5-(trifluoromethyl)pyridin-2-yl]-1H-pyrazole-4-carboxylic acid chloride (1.34 g) described in Reference Example 180 under ice-cooling, and stirred at room temperature for 1.5 hours. After completion of the reaction, the solvent was evaporated, and saturated sodium bicarbonate water was added thereto. The insoluble matter was collected by filtration, washed with water, and then dried in vacuo to give the titled compound as a pale yellow solid (1.66 g). MS (ESI) m/z: 440 (M+H)+.
