4-(4-(5-Chloroimidazo[1,2-c]pyrimidin-7-yl)phenyl)morpholine (0.0400 g, 0.127 mmol), 4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-1H-pyrazole (0.0370 g, 0.191 mmol) and potassium carbonate (0.0527 g, 0.381 mmol) were suspended in a mixture of DME (2 mL) and water (1 mL) and de-gassed with argon for 5 minutes. Tetrakis(triphenylphosphine)palladium (0) (0.00734 g, 0.00635 mmol) was added and the reaction sealed and heated at 100° C. for 2 hours. The reaction mixture was concentrated under reduced pressure. The residue 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%-6% (9:1 MeOH:NH4OH)/DCM) to furnish 4-(4-(5-(1H-pyrazol-4-yl)imidazo[1,2-c]pyrimidin-7-yl)phenyl)morpholine (0.0160 g, 0.046 mmol, 36.4% yield). MS (apci) m/z=347.1 (M+H).
