Versuchsvorschrift

To a solution of 5-chloropyrazolo[1,5-a]pyrimidine-3-carbonyl chloride (400.4 mg, 1.853 mmol, 1.16 equiv) in dichloromethane (6 mL) was added 3-(2,5-dimethylphenyl)-1H-pyrazol-4-amine (300.0 mg, 1.602 mmol, 1.0 equiv) and triethylamine (0.70 mL, 5.0 mmol, 3.1 equiv) at room temperature. After 14 hours, the reaction mixture was partitioned between dichloromethane and half-saturated aqueous sodium bicarbonate solution. The aqueous layer was extracted once with dichloromethane. The combined organic portions are dried over magnesium sulfate, filtered, and concentrated to yield 5-chloro-N-(3-(2,5-dimethylphenyl)-1H-pyrazol-4-yl)pyrazolo[1,5-a]pyrimidine-3-carboxamide, which was carried forward without purification. LCMS (ESI) m+H=367.1.
