Reaction Steps

4-(3-Bromo-imidazo[1,2-b]pyridazin-7-yl)-1-(3-piperidin-1-yl-propyl)-1H-pyridin-2-one (1.0 eq, 0.096 mmol, 40 mg), [3-(1H-pyrazol-1-yl)phenyl]boronic acid (1.50 eq, 0.144 mmol, 28.5 mg) and Na2CO3 (2.0 eq, 0.192 mmol, 20.4 mg) are dissolved in DME/H2O (3/1 ml) and PdCl2(PPh3)2 (0.1 eq, 0.0096 mmol, 6.74 mg) is added. The reaction mixture is then heated in a microwave at 120° C. for 10 min. At the completion of this time the solvent is removed in vacuo and the product is purified by flash column chromatography eluting with CH2Cl2/MeOH (80:20) to give 1-(3-piperidin-1-yl-propyl)-4-[3-(3-pyrazol-1-yl-phenyl)imidazo[1,2-b]pyridazin-7-yl]-1H-pyridin-2-one as a yellow solid; [M+H]+=480
