Reaction Steps

Under cooling in an ice bath, 4-(trifluoromethyl)benzoyl chloride (8.26 g) was added dropwise to a chloroform (35 mL) solution that contained 1-methyl-1H-pyrazol-5-amine (3.50 g) and triethylamine (5.50 mL), and the obtained solution was then stirred for 2 hours. Thereafter, the reaction solution was diluted with chloroform, and was then washed with a saturated sodium hydrogencarbonate aqueous solution and a saturated saline. The organic layer was dried over anhydrous sodium sulfate, and was then concentrated under a reduced pressure. The obtained solid was washed with diisopropyl ether, so as to obtain the title compound (6.75 g) in the form of a colorless solid.
