実験手順

3-[2-Amino-3-(2-Chloro-pyridin-4-yl)-imidazo-[1,2-b]-pyridazin-7-yl]-N-methyl benzamide (1 eq, 0.146 mmol, 79 mg) and phenyl boronic acid (1.5 eq, 0.219 mmol, 27.5 mg) are dissolved in DME (1.5 ml) and water (0.4 ml) and Na2CO3 (3 eq, 0.438 mmol, 46.4 mg) are added. PdCl2(PPh3)2 (0.05 eq, 0.008 mmol, 5.12 mg) is then added and the reaction mixture is heated using microwave radiation at 120° C. for 15 min. At the completion of this time the solvent is removed in vacuo and the reaction mixture is purified by flash column chromatography eluting with 9:1 DCM/MeOH to yield 3-(2-Amino-3-(2-phenyl-pyridin-4-yl)imidazo [1,2-b]pyridazin-7-yl]-N-methyl-benzamide as a yellow solid; [M+H]+=421
