Reaction Steps

Following the procedure of Example 91, to a solution containing 8-bromo-N-(2-chloro-4-(4-methylpiperazine-1-carbonyl)phenyl)-N-methyl-4,5-dihydrobenzo[b]thieno[2,3-d]oxepine-2-carboxamide (0.095 g, 0.16 mmol) in 1,4-dioxane (2.00 mL, 25.6 mmol;) was added 4,5-bis(diphenylphosphino)-9,9-dimethylxanthene (XantPhos, 9.6 mg, 0.016 mmol;), acetamide (15 mg, 0.25 mmol;), and cesium carbonate (120 mg, 0.36 mmol) then degassed with nitrogen gas for 15 min. To the reaction mixture was added tris(dibenzylideneacetone)dipalladium(0) (Pd2(dba)3, 7.6 mg, 0.0083 mmol;). The reaction mixture was heat at 100° C. for 18 h. The crude product was submitted for rHPLC to give 147 (5.5%). MS: (ESI+) 553.2
