실험 절차

A 1.0M solution of diisobutylaluminium hydride in hexane was added dropwise into a solution of ethyl 4-(7-(butyl)-3-mesityl-2,5-dimethylpyrazolo[1,5-a]pyrimidin-6-yl)butanoate (320 mg, 0.71 mmol) in tetrahydrofuran (10 mL) under nitrogen stream, followed by stirring for 30 minutes. After Celite was added, the mixture was treated by adding ethyl acetate and water dropwise, and the insoluble matters were filtered off. The solution was extracted with ethyl acetate, dried over anhydrous magnesium sulfate and evaporated, to give the title compound (320 mg) as a brown oil.
