Reaction Steps
A mixture of tert-butyl 6-amino-3,4-dihydroisoquinoline-2(1H)-carboxylate (3 g, 12 mmol), 3,5-dibromo-1-methylpyrazin-2(1H)-one (2.68 g, 10 mmol), and triethylamine (1.5 g, 15 mmol) in IPA (50 mL) was heated at 70° C. for 15 h. The mixture was cooled to room temperature. The resulting yellow solids were collected by filtration and dried in vacuum to afford 120a as a yellow solid (2.83 g, 65%).MS: [M+H]+ 435.
