Procedure

To a solution of 6-chloro-N-(6-(2-methylpyrrolidin-1-yl)pyridin-2-yl)imidazo[1,2-b]pyridazin-8-amine (500 mg, 1.52 mmol) and 3-cyanophenylboronic acid (336 mg, 2.29 mmol) in dioxane/H2O (10 mL/2 mL) was added Na2CO3 (322 mg, 3.04 mmol) followed by Pd(dba)2 (175 mg, 0.30 mmol) and X-Phos (73 mg, 0.15 mmol) under nitrogen with stirring. The mixture was stirred at reflux for 15 h under nitrogen. After cooling, the solvent was concentrated in vacuo. The residue was purified by chromatography (silica, ethyl acetate) to give 3-(8-(6-(2-methylpyrrolidin-1-yl)pyridin-2-ylamino)imidazo[1,2-b]pyridazin-6-yl)benzonitrile (310 mg, 52%) as a yellow oil. LC-MS: 396.2 [M+H]+, tR=1.89 min.
