Reaction Steps
A mixture of 6-bromo-N-[(4-methoxyphenyl)methyl]pyrazin-2-amine (0.9932 mmol; 768.8 mg), tributyl-[1-(6-fluoro-2-pyridyl)pyrazolo[4,3-c]pyridin-6-yl]stannane (2.173 mmol; 1093 mg), tricyclohexylphosphine (0.1192 mmol; 33.42 mg) and Tris(dibenzylideneacetone)dipalladium (0) (0.04966 mmol; 45.47 mg) in N,N-Dimethylacetamide (15 mL) was purged with Argon for 1 min. The reaction mixture was sealed and heated at 150° C. under microwave for 45 min. The mixture was partitioned between EtOAc and water. The organic layer was concentrated and the residue was purified on silica eluted with 0 to 100% EtOAc in Heptane to afford 6-[1-(6-fluoro-2-pyridyl)pyrazolo[4,3-c]pyridin-6-yl]-N-[(4-methoxyphenyl)methyl]pyrazin-2-amine (316.3 mg, 48%).
