Procedure
In a 2 mL flask, 2-(3-(4-(7-(1-methyl-1H-pyrazol-4-yl)imidazo[1,2-c]pyrimidin-5-yl)-1H-pyrazol-1-yl)azetidin-3-yl)acetonitrile hydrochloride (Example 62; 15 mg, 0.035 mmol) was suspended in acetonitrile (350 μL, 0.035 mmol). To this was added triethylamine (19 μL, 0.14 mmol), followed by propionaldehyde (25 μL, 0.35 mmol). After stirring for 30 minutes, NaBH(OAc)3 (37 mg, 0.17 mmol) was added. After the reaction was complete, it was quenched with saturated bicarbonate solution and extracted with EtOAc. The organic layer was washed with brine, dried with MgSO4, filtered and concentrated in vacuo. The residue was purified by reverse phase HPLC using a 0-100% acetonitrile/water gradient to afford 2-(3-(4-(7-(1-methyl-1H-pyrazol-4-yl)imidazo-[1,2-c]pyrimidin-5-yl)-1H-pyrazol-1-yl)-1-propylazetidin-3-yl)acetonitrile (7.1 mg, 51% yield) as a white solid. MS (apci) m/z=402.2 (M+H).
