Reaction Steps

To 5-((5-(3-chlorophenylamino)-7-(piperidin-4-ylamino) pyrazolo[1,5-a]pyrimidin-3-yl)methylene) imidazolidine-2,4-dione (30 mg, 0.06 mmol) in THF and AcOH (4.8 mg, 0.08 mmol) was added acetaldehyde (2.0 mL, 0.2 mmol) and sodium triacetoxy borohydride (85.0 mg, 0.4 mmol). The mixture was stirred at room temperature for 0.5 hour. The reaction mixture was concentrated, diluted with MeOH, and purified by prep HPLC to yield 5-((5-(3-chlorophenylamino)-7-(1-ethylpiperidin-4-ylamino) pyrazolo[1,5-a]pyrimidin-3-yl)methylene) imidazolidine-2,4-dione. LCMS (M+1=481)
