Reaction Steps

To a solution of 3-(5-chloro-2-methylphenyl)-1-methyl-1H-pyrazol-4-amine (182.9 mg, 0.4826 mmol, 1.2 equiv) in dichloromethane (5 mL) was added 5-chloropyrazolo[1,5-a]pyrimidine-3-carbonyl chloride (91.2 mg, 0.411 mmol, 1.0 equiv) and triethylamine (0.30 mL, 2.2 mmol, 5.2 equiv) at room temperature. After 16 hours, the reaction mixture was partitioned between ethyl acetate and saturated aqueous sodium bicarbonate solution. The organic layer was dried over magnesium sulfate, filtered, and concentrated to give 143.1 mg (87%) of 5-chloro-N-(3-(5-chloro-2-methylphenyl)-1-methyl-1H-pyrazol-4-yl)pyrazolo[1,5-a]pyrimidine-3-carboxamide which was carried forward without purification. LCMS (ESI) m+H=401.0.
