Reaction Steps
A microwave vial equipped with a magnetic stirrer was charged with 116a (600 mg, 1.65 mmol), 5-(4-(oxetan-3-yl)piperazin-1-yl)pyridin-2-amine (390 mg 1.67 mmol), cesium carbonate (1.09 g, 3.34 mmol), tris(dibenzylideneacetone)dipalladium(0) (152 mg, 0.167 mmol), Xantphos (193 mg, 0.334 mmol), and dioxane (10 mL). After bubbling nitrogen through the suspension for 10 minutes, the reaction was heated at 120° C. overnight. It was then cooled to room temperature and filtered. The filtrate was concentrated under reduced pressure and the residue was washed with a mixed solvent of petroleum ether and ethyl acetate (15 mL, 2:1) to afford 116b as a yellow solid (720 mg, 85%). MS-ESI: [M+H]+ 515.2
