実験手順

Pyridine (0.31 g (3.9 mmol)) and dimethyl sulfoxide (0.03 g (0.4 mmol)) were added to a solution of 1.0 g (3.9 mmol) of 2-chlorosulfonyl-5-chloro-7-methyl-[1,2,4]triazolo[1,5-a]pyridine and 0.76 g (3.9 mmol) of 4-amino-1-ethyl-5-methyl-3-(trifluoromethyl)pyrazole in 15 mL of acetonitrile at ambient temperature with stirring. After 18 hours, the volatiles were removed by evaporation under reduced pressure and the residue was partitioned between dichloromethane and water, stirring for 10 min before separation. The solids were recovered by filtration and washed with ether. They were then resuspended in water and the mixture stirred for 30 min. The solids were recovered by filtration, washed with ether, and dried under reduced pressure at 40° C. overnight. The resulting 1.24 g (68 percent of theory) of white powder melting at 224°-226° C. was the title compound.
