Procedure

A 100-mL single-neck round-bottomed flask equipped with a reflux condenser was charged with (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 (280 mg, 0.8 mmol), (S)-3-(5-(2-ethyl-4-(oxetan-3-yl)piperazin-1-yl)pyridin-2-ylamino)-1-methyl-5-(4,4,5,5-tetra-methyl-1,3,2-dioxaborolan-2-yl)pyridin-2(1H)-one 161f (500 mg, 0.96 mmol), Pd(dppf)Cl2 (33 mg, 0.040 mmol), K3PO4 (360 mg, 1.6 mmol), sodium acetate trihydrate (240 mg, 1.6 mmol), and acetonitrile (100 mL). The system was evacuated and refilled with N2. The reaction mixture was heated at 100° C. for 2 h. It was then cooled to room temperature and filtered. The filtrate was concentrated under reduced pressure and the resulting residue was purified by silica-gel column chromatography eluting with 25:1 dichloromethane/methanol to afford 164a (320 mg, 60%) as a yellow brown solid. MS-ESI: [M+H]+ 677.3.
