Reaction Steps

To 5-((5-(3-chlorophenylamino)-7-(piperidin-4-ylamino) pyrazolo[1,5-a]pyrimidin-3-yl)methylene) imidazolidine-2,4-dione (20 mg, 0.04 mmol) in THF and AcOH (4.8 mg, 0.08 mmol) was added acetone (2.0 mL, 0.2 mmol) and sodium triacetoxy borohydride (85.0 mg, 0.4 mmol). The mixture was heated at 60° C. for one hour. Saturated sodium bicarbonate solution was added to the reaction mixture. The mixture was extracted with ethyl acetate and dried over sodium sulfate. Then the mixture was, diluted with MeOH, and purified by prep HPLC to yield 5-((5-(3-chlorophenylamino)-7-(1-isopropylpiperidin-4-ylamino) pyrazolo[1,5-a]pyrimidin-3-yl)methylene) imidazolidine-2,4-dione. LCMS (M+1=495)
