Procedure

A round-bottomed flask was charged with 4-chloro-2-[(1R,11S)-7-oxo-3,6-diazatetracyclo[9.2.1.02,10.03,8]tetradeca-2(10),8-dien-6-yl]pyridine-3-carbaldehyde 170b (200 mg, 0.59 mmol), 1-methyl-3-({5-[(2S)-2-methyl-4-(oxetan-3-yl)piperazin-1-yl]pyridin-2-yl}amino)-5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-1,2-dihydropyridin-2-one 191j (400 mg, 0.88 mmol), PdCl2(dppf) (50 mg, 0.06 mmol), K3PO43 water (300 mg, 1.20 mmol), sodium acetate (100 mg, 1.20 mmol), acetonitrile (15 mL), and water (1.5 mL). After three cycles of vacuum/argon flush, the mixture was heated at 100° C. for 3 h. It was then filtered and the filtrate was evaporated under reduced pressure. The residue was purified with silica-gel column chromatography eluting with 1:20 methanol/dichloromethane to afford 174a as a red solid (170 mg, 44%). MS-ESI: [M+H]+ 661.3
