5-Chloro-7-(4-(1-methylpiperidin-4-yl)phenyl)imidazo[1,2-c]pyrimidine (0.120 g, 0.367 mmol), 4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-1H-pyrazole (0.107 g, 0.551 mmol) and potassium carbonate (0.152 g, 1.10 mmol) were suspended in a mixture of DME (5 mL) and water (2 mL) and purged with argon for 5 minutes. Tetrakis(triphenylphosphine)palladium (0) (0.02121 g, 0.01836 mmol) was added and the reaction sealed and heated at 100° C. for 18 hours. The reaction mixture was cooled to ambient temperature and diluted with water and filtered. The solids were washed with acetone and then dried under high vacuum to afford 7-(4-(1-methylpiperidin-4-yl)phenyl)-5-(1H-pyrazol-4-yl)imidazo[1,2-c]pyrimidine (0.0310 g, 0.0865 mmol, 23.55% yield). MS (apci) m/z=359.2 (M+H).
