反応手順
Hydantoin (2.7 mg, 0.027 mmol) and 3-chloro-4-(7-(cyclopropylamino)-3-formyl-6-methylpyrazolo[1,5-a]pyrimidin-5-ylamino)benzonitrile (10 mg, 0.027 mmol) were dissolved in ethanol (0.4 mL) along with piperidine (3 uL, 0.03 mmol). The reaction was heated at 80° C. After 10 hours, the reaction was cooled to r.t., diluted with water, and the precipitate was collected and washed with water, 1:1 ethanol:water, then ethanol. The bright yellow solid was dried in vacuo to give 3-chloro-4-(7-(cyclopropylamino)-3-((2,5-dioxoimidazolidin-4-ylidene)methyl)-6-methylpyrazolo[1,5-a]pyrimidin-5-ylamino)benzonitrile (7 mg, 58% yield).
