Procedure

A 100-mL single-neck round-bottomed flask equipped with a magnetic stirrer and a reflux condenser was charged with 109a (75 mg, 0.2 mmol), 1-methyl-3-(5-(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 101l (94 mg, 0.2 mmol), Pd(dppf)Cl2 (17 mg, 0.02 mmol), K3PO4.3H2O (140 mg, 0.6 mmol), and tetrahydrofuran (10 mL). After three cycles of vacuum/argon flush, the mixture was heated at reflux for 4 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 dichloromethane/methanol (40:1) to 109b as yellow solid (60 mg, 47%). MS: [M+H]+ 666.
