Reaction Steps

To N-(7-(cyclopropylamino)-3-formylpyrazolo[1,5-a]pyrimidin-5-yl) cyclopropanecarboxamide (74 mg, 0.26 mmol) in 1.0 mL ethanol was added hydantoin (26 mg, 0.26 mmol) and piperidine (24 ul). The reaction was heated at 80° C. for two hours. The reaction mixture was cooled to room temperature, concentrated and diluted with MeOH. The product was purified by prep HPLC to yield 14 mg (20% yield) (Z)-N-(7-(cyclopropylamino)-3-((2,5-dioxoimidazolidin-4-ylidene)methyl)pyrazolo[1,5-a]pyrimidin-5-yl)cyclopropanecarboxamide.
