Procedure

A 50-mL round-bottomed flask equipped with a reflux condenser was charged with 196c (258 mg, 0.70 mmol), 4-chloro-2-{4,4-dimethyl-9-oxo-1,10-diazatricyclo[6.4.0.02,6]dodeca-2(6),7-dien-10-yl}pyridine-3-carbaldehyde 108a (240 mg, 0.70 mmol), K3PO4 (297 mg, 1.4 mmol), sodium acetate (190 mg, 1.4 mmol), 1,1′-bis(diphenylphosphino)ferrocenedichloropalladium(II) (29 mg, 0.035 mmol), acetonitrile (10 mL), and water (0.5 mL). After bubbling nitrogen through the mixture for 30 minutes, it was heated at 100° C. under N2 protection for 1 h. Analysis of reaction by LCMS showed completed conversion to the desired product. The mixture was cooled to room temperature and diluted with dichloromethane (20 mL) and water (20 mL). The aqueous layer was separated and extracted with dichloromethane (3×20 mL). The combined organic layer was dried over Na2SO4, filtered, and concentrated under reduced pressure. The dark residue was purified by silica-gel column chromatography eluting with dichloromethane/methanol (80/1 to 30/1) to afford 196d (220 mg, 57%) as yellow solid. MS-ESI: [M+H]+ 549
