Reaction Conditions

Temperature	100 °C

Reaction Steps

A mixture of 101h (300 mg, 0.70 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 (332 mg, 0.70 mmol), CH3COONa (114 mg, 1.4 mmol), K3PO4 (368 mg, 1.4 mmol), PdCl2(dppf) (56 mg, 0.07 mmol), CH3CN (25 mL), and H2O (1 mL) was heated at 100° C. for 3 hours. It was then evaporated and the residue was purified by silical-gel column eluting with methylene chloride/methanol (30:1) to afford 101i (293 mg, yield 41%) as a brown solid. MS: (M+H)+ 710.
