実験手順
4-chloroaniline (0.355 g, 2.78 mmol) was added to a well-stirred absolute ethanol solution of 7-chloro-5-methyl-2-(trifluoromethyl)-[1,2,4]triazolo[1,5-a]pyrimidine (0.547 g, 2.32 mmol, 15-20 mL). After stirring for 6-8 hours at room temperature, the desired product crystallized and was then filtered. Subsequent purification using column chromatography gave the final product in 66% yield.
