Reaction Steps
A 25 mL sealed tube was charged with 4-fluoro-2-(1-oxo-3,4,6,7,8,9-hexahydropyrazino[1,2-a]indol-2(1H)-yl)-6-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)benzyl acetate (210d) (500 mg, 1.0 mmol), 5-bromo-1-methyl-3-(5-methyl-4,5,6,7-tetrahydropyrazolo[1,5-a]pyrazin-2-ylamino)pyridin-2(1H)-one (146a) (350 mg, 1.0 mmol), CH3COONa (170 mg, 2.0 mmol), K3PO4 (552 mg, 2.0 mmol), PdCl2(dppf) (85 mg, 0.1 mmol) suspended in CH3CN (25 mL) and H2O (1 mL). The mixture was heated at 110° C. for 2 hours. It was then evaporated and the residue was purified by silical-gel column eluting with 20:1 methylene chloride/methanol to give 234a as a brown solid (400 mg, 63%). MS: (M+H)+ 614.
