A mixture of 5-(3-bromophenyl)-1-(2-((trimethylsilyl)methoxy)ethyl)-1H-pyrazol-4-amine (533 mg, 1.45 mmol), in tetrahydrofuran (5 mL) was added of pyrazolo[1,5-a]pyrimidine-3-carbonyl chloride (262 mg, 1.45 mmol) in tetrahydrofuran (5 mL) at 0° C. After addition, the mixture was warmed to room temperature, and then stirred overnight at this temperature. The mixture was concentrated to give 742 mg (99%) of N-(5-(3-bromophenyl)-1-(2-((trimethylsilyl)methoxy)ethyl)-1H-pyrazol-4-yl)pyrazolo[1,5-a]pyrimidine-3-carboxamide, which was carried forward without purification. LCMS (ESI) m+H=513.1.
