実験手順

To the reaction flask, 5,7-dichloropyrazolo[1,5-a]pyrimidine (896 mg, 4.8 mmol) was added along with tert-butyl 4-aminopiperidine-1-carboxylate (954 mg, 4.8 mmol), triethylamine (664 μL, 4.8 mmol), and acetonitrile (16 mL). The reaction was heated at 100° C. for 12 hours then cooled to room temperature, diluted with water, filtered and washed with water. The product, tert-butyl 4-(5-chloropyrazolo[1,5-a]pyrimidin-7-ylamino)piperidine-1-carboxylate, was collected as a solid in quantitative yield and dried under vacuum overnight. LCMS (M+1=352)
