4-(4-(5-(3-methyl-1H-pyrazol-4-yl)imidazo[1,2-c]pyrimidin-7-yl)phenyl)morpholine (0.0690 g, 0.191 mmol), 3-cyclopentylacrylonitrile (Table 1, compound g; 0.0696 g, 0.574 mmol) and DBU 0.0661 mL, 0.479 mmol) were suspended in DMF (3 mL) and stirred overnight. The reaction mixture was partitioned between saturated aqueous NaHCO3 and EtOAc. The organics were washed with brine, dried, MgSO4 and concentrated under reduced pressure to afford the crude material, which was purified by flash column chromatography (eluant: 0.5-2% (9:1, MeOH:NH4OH)/DCM) to furnish 3-cyclopentyl-3-(3-methyl-4-(7-(4-morpholinophenyl) imidazo[1,2-c]pyrimidin-5-yl)-1H-pyrazol-1-yl)propanenitrile (0.0380 g, 0.078905 mmol, 41.2% yield). MS (apci) m/z=482.2 (M+H).
