실험 절차

4-(7-(cyclopropylamino)-3-formylpyrazolo[1,5-a]pyrimidin-5-ylamino)benzonitrile (75 mg, 0.24 mmol) was suspended in EtOH (2.4 mL). Hydantoin (36 mg, 0.35 mmol) and piperidine (36 μL, 0.35 mmol) were added and the reaction was heated to 80° C. After 15 h, the solution was filtered while warm and the filter cake was washed with warm EtOH (3 mL) to give (Z)-4-(7-(cyclopropylamino)-3-((2,5-dioxoimidazolidin-4-ylidene)methyl)pyrazolo[1,5-a]pyrimidin-5-ylamino)benzonitrile (76 mg, 80%) as a bright yellow solid. LCMS (ES): >90% pure, m/z 401 [M+1]+.
