Reaction Steps

Hydantoin (7.5 mg, 0.08 mmol) and 2-(4-(7-(cyclopropylamino)-3-formyl-6-methylpyrazolo[1,5-a]pyrimidin-5-yl)piperazin-1-yl)nicotinonitrile (15 mg, 0.04 mmol) were dissolved in ethanol (0.5 mL) along with piperidine (8 uL, 0.08 mmol). The reaction was heated at 80° C. for 1 hour in the microwave. 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 2-(4-(7-(cyclopropylamino)-3-((2,5-dioxoimidazolidin-4-ylidene)methyl)-6-methylpyrazolo[1,5-a]pyrimidin-5-yl)piperazin-1-yl)nicotinonitrile (3 mg, 17% yield). LCMS (M+1=485)
