2-(4-(4-(7-(1-methyl-1H-pyrazol-4-yl)imidazo[1,2-c]pyrimidin-5-yl)-1H-pyrazol-1-yl)piperidin-4-yl)acetonitrile hydrochloride (15.8 mg, 0.0318 mmol) was suspended in acetonitrile (318 μL, 0.0318 mmol). To this was added triethylamine (17.7 μL, 0.127 mmol) to freebase, followed by formaldehyde (25.8 mg, 0.318 mmol). After 30 minutes, NaBH(OAc)3 (33.7 mg, 0.159 mmol) was added. After stirring for 30 minutes, the reaction mixture was diluted in saturated sodium bicarbonate and EtOAc. The aqueous layer was back-extracted with DCM. The combined organic layer was washed with brine, dried with MgSO4, filtered and concentrated. Purification of the resulting crude material by reverse phase HPLC using a 0-100% acetonitrile/water gradient afforded 2-(1-methyl-4-(4-(7-(1-methyl-1H-pyrazol-4-yl)imidazo[1,2-c]pyrimidin-5-yl)-1H-pyrazol-1-yl)piperidin-4-yl)acetonitrile (2.0 mg, 16% yield). MS (apci) m/z=402.1 (M+H).
