실험 절차

To the reaction flask, 5,7-dichloropyrazolo[1,5-a]pyrimidine (1.6 g, 8.2 mmol) was added along with tert-butyl 3-aminobenzoate (1.7 g, 8.7 mmol), triethylamine (1.2 mL, 8.6 mmol), and t-butyl alcohol (22 mL). The reaction was heated at 100° C. for 6 hours then diluted with water, filtered and washed with water. The product, tert-butyl 3-(5-chloropyrazolo[1,5-a]pyrimidin-7-ylamino)benzoate, was collected as a solid in quantitative yield after drying under vacuum overnight. LCMS (M+1=345)
