Procedure

A 50-mL single-neck round-bottomed flask equipped with a magnetic stirrer and a reflux condenser was charged with acetonitrile (30 mL), 4-chloro-2-[(1S,11R)-7-oxo-3,6-diazatetracyclo[9.2.1.02,10.03,8]tetradeca-2(10),8-dien-6-yl]pyridine-3-carbaldehyde 167g (170 mg, 0.50 mmol), (S)-1-methyl-3-(5-(2-methyl-4-(oxetan-3-yl)piperazin-1-yl)pyridin-2-ylamino)-5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)pyridin-2(1H)-one 130f (336 mg, 0.70 mmol), water (3 mL), and potassium acetate (147 mg, 1.5 mmol). After bubbling argon through the suspension for 30 minutes, 1,1′-bis(diphenylphosphino)ferrocenedichloropalladium(II) (408 mg, 0.05 mmol) was added. The system was subjected to three cycles of vacuum/argon flush and heated at 80° C. for 3 h. It was then cooled to room temperature and filtered. The solid was washed with dichloromethane (2×100 ml). The combined filtrate was concentrated under reduced pressure and the residue was purified by silica-gel column chromatography eluting with dichloromethane/methanol (50:1 to 30:1) to afford 171a (95 mg, 29%) as a light yellow solid. MS-ESI: [M+H]+ 661.3
