Reaction Steps
A mixture of 207b (1.84 g, 10.3 mmol), XantPhos (714 mg, 1.24 mmol), Pd2 dba3 (755 mg, 0.82 mmol), 3,5-dibromo-1-methylpyridin-2(1H)-one (3.27 g, 12.3 mmol) and Cs2CO3 (10 g. 30.9 mmol) in 1,4-dioxane (50 mL) was heated at reflux for 2 h. After the completion of the reaction, the mixture was filtered off, and washed with MeOH (100 mL). The filtrate was evaporated in vacuo and the residue was purified on reverse phase Combi-flash to give 207c (2.11 g, 54%). MS: [M+H]+ 365.
