Procedure

A mixture of (206e (2 g, 8.3 mmol), 3,5-dibromo-1-methylpyridin-2(1H)-one (2.2 g, 8.3 mmol), XantPhos (482 mg, 0.83 mmol), Pd2(dba)3 (762 mg, 0.83 mmol) and Cs2CO3 (6.8 g, 21 mmol) in dioxane (80 mL) was heated at 100° C. for 15 h under nitrogen. It was then filtered, evaporated in vacuo, and purified by silical-gel column eluting with 1:2 petroleum ether/ethyl acetate to give 206f as a yellow solid (2.7 g, 77%). MS: (M+H)+ 426.
