Reaction Steps

A mixture of 2,6-dibromopyrazine (3.431 mmol; 816.1 mg), (4-methoxyphenyl)methanamine (3.431 mmol; 470.6 mg; 0.4452 mL), and N-Methylmorpholine (8.577 mmol; 876 mg; 0.952 mL) in 1-methyl-2-pyrrolidinone (10 mL) in a sealed pressure vial was heated at 100° C. overnight. The mixture was poured into water, and extracted with EtOAc. The organic layer was concentrated. The residue was purified on silica eluted with 0 to 100% EtOAc in DCM to afford 6-bromo-N-[(4-methoxyphenyl)methyl]pyrazin-2-amine (768.8 mg, 29%).
