Reaction Steps

Into the mixture of (R)-4-((R)-1-((6-chloro-3-methyl-3H-imidazo[4,5-c]pyridin-4-yl)oxy)ethyl)-1-((R)-1-(4-methoxyphenyl)ethyl)pyrrolidin-2-one 2.05 (60 mg, 0.14 mmol) and 1-(oxetan-3-yl)-4-(6-(tributylstannyl)pyridin-3-yl)piperazine 7.16 (78 mg, 0.154 mmol) in dioxane (3 mL) was added tetrakis(triphenylphosphine)palladium (16 mg) and KF (24 mg). Then the mixture was flushed with Argon, and heated by microwave at 140° C. for 20 min. The reaction was diluted with 50 mL of ethyl acetate and filtered to remove the solid. After removal of solvent, the residue was purified by silica gel column chromatography to provide 86 mg of (R)-1-((R)-1-(4-methoxyphenyl)ethyl)-4-((R)-1-((3-methyl-6-(5-(4-(oxetan-3-yl)piperazin-1-yl)pyridin-2-yl)-3H-imidazo[4,5-c]pyridin-4-yl)oxy)ethyl)pyrrolidin-2-one. LCMS [M+H]+: 612.27.
