Reaction Steps

3-Imidazo[1,2-b]pyridazin-3-ylethynyl-4-methyl-phenylamine TFA salt (200 mg, 0.55 mmol) was dissolved in DMF (5 mL) with 5-(4-fluoro-phenyl)-2-methanesulfonyl-1H-imidazole-4-carboxylic acid (204 mg, 0.72 mmol) at RT. HATU (300 mg, 0.79 mmol) was added, followed by DIEA (0.6 mL, 3.44 mmol). The mixture was stirred for 20 h. Water (10 mL) was added and the mixture was extracted with EtOAc (30 mL). The organic layer was concentrated and the residue was dissolved in minimum amount of DMSO and purified by prep HPLC. 140 mg of title compound was obtained after lyophilization of pure fractions. LC-MS [M+H] 515.2.
