Procedure

A sealed tube equipped with a magnetic stirrer was charged with 226a (279 mg, 0.80 mmol), (2-{4,4-dimethyl-9-oxo-1,10-diazatricyclo[6.4.0.02,6]dodeca-2(6),7-dien-10-yl}-4-(tetramethyl-1,3,2-dioxaborolan-2-yl)pyridin-3-yl) methyl acetate 199e (1.53 g, 3.2 mmol), Pd2(dba)3 (73.2 mg, 0.080 mmol), tricyclohexyl-phospine (44.6 mg, 0.16 mmol), cesium carbonate (521.6 mg, 1.6 mmol), 1,4-dioxane (10 mL), and water (8 drops). After three cycles of vacuum/argon flush, the mixture was stirred at 110° C. for 4 h. It was then filtered and the filtrate was evaporated in vacuo. The residue was purified by silica-gel column chromatography eluting with 40:1 ethyl acetate/methanol to afford 226b as a yellow solid (120 mg, 23%). MS-ESI: [M+H]+ 667.3
