Reaction Steps

In step 14-1, 2-(methylthio)-4-(tributylstannyl)pyrimidine (4.3 g, 13.2 mmol) and Pd(PPh3)4 (196 mg, 0.17 mmol) were added to a solution of (R)-3-(6-bromopyridin-2-yl)-6-(2-(3-fluorophenyl)pyrrolidin-1-yl)imidazo[1,2-b]pyridazine (14-1) (1.5 g, 3.4 mmol) in toluene (35 mL). The mixture was degassed using N2 for 15 minutes and then heated at 110° C. for 2 hours. All the solvents were removed. The resulting mixture was purified by column chromatography (silica gel, EtOAc/CH3OH, 0 to 10% gradient) to give (R)-6-(2-(3-fluorophenyl)pyrrolidin-1-yl)-3-(6-(2-(methylthio)pyrimidin-4-yl)pyridin-2-yl)imidazo[1,2-b]pyridazine (14-2) as a light-yellow foam. LC/MS: 484.2 (MH+).
