Cesium carbonate → N-(3-(5-cyano-2-methoxyphenyl)-1-((1-methyl-1H-1,2,4-triazol-3-yl)methyl)-1H-pyrazol-4-yl)pyrazolo[1,5-a]pyrimidine-3-carboxamide

Participants

Reaction Steps

N-(3-(5-cyano-2-methoxyphenyl)-1H-pyrazol-4-yl)pyrazolo[1,5-a]pyrimidine-3-carboxamide (0.15 g, 0.42 mmol) was dissolved in 10 mL of DMF, then 3-(chloromethyl)-1-methyl-1H-1,2,4-triazole hydrochloride (82 mg, 0.63 mmol) and Cs2CO3 (0.41 g, 1.26 mmol) were added. The mixture was stirred at room temperature for 2 hours, then filtered through celite and purified by reverse phase HPLC to give 44.8 mg (23%) of N-(3-(5-cyano-2-methoxyphenyl)-1-((1-methyl-1H-1,2,4-triazol-3-yl)methyl)-1H-pyrazol-4-yl)pyrazolo[1,5-a]pyrimidine-3-carboxamide.
