Procedure

A 100-mL round-bottomed flask equipped with a reflux condenser was charged with 4-chloro-2-{6-oxo-8-thia-4,5-diazatricyclo[7.4.0.02,6]trideca-1(9),2(7),3-trien-5-yl}pyridine-3-carbaldehyde 124a (84 mg, 0.24 mmol), (R)-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 151g (173 mg, 0.36 mmol), PdCl2(dppf) (20 mg, 0.024 mmol), K3PO4 (100 mg, 0.48 mmol), sodium acetate (40 mg, 0.48 mmol), acetonitrile (20 mL), and water (2 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 by silica-gel column chromatography eluting with 1:20 methanol/dichloromethane to afford 154a as a red solid (112 mg, 70%). MS-ESI: [M+H]+ 665
