Reaction Steps

Hydantoin (3 mg, 0.03 mmol) and 5-(4-(1H-pyrazol-1-yl)phenylamino)-7-(cyclopropylamino)-2-methylpyrazolo[1,5-a]pyrimidine-3-carbaldehyde (12 mg, 0.03 mmol) were dissolved in ethanol (0.4 mL) along with piperidine (3 uL, 0.03 mmol). The reaction was heated at 80° C. in the microwave for 2 hours. The reaction was then cooled to r.t., diluted with water, and the precipitate was collected and washed with water, 1:1 ethanol:water, then ethanol. The yellow solid was dried in vacuo to give 5-((5-(4-(1H-pyrazol-1-yl)phenylamino)-7-(cyclopropylamino)-2-methylpyrazolo[1,5-a]pyrimidin-3-yl)methylene)imidazolidine-2,4-dione (9.5 mg, 65% yield). LCMS (M+1=456)
