Reaction Steps

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 (0.075 g, 0.13 mmol) in tetrahydrofuran (1.50 mL, 18.5 mmol), 2.00 M of methylamine in tetrahydrofuran (0.196 mL) was added molybdenumhexacarbonyl (34.4 mg, 0.130 mmol), trans-di(mu-acetato)bis[o-(di-o-tolylphosphino)benzyl]dipalladium (II) (18.3 mg, 0.0196 mmol) then 1,8-diazabicyclo[5.4.0]undec-7-ene (9.75 uL, 0.0652 mmol) and capped quickly to prevent CO gas from escaping. The reaction mixture was heated in a microwave at 150° C. for 20 min. The reaction mixture was diluted with EtOAc then filtered thru celite. The combined organics were dried (Na2SO4), filtered and concentrated. The crude was submitted for RP HPLC to give 181 (yield 32%). MS: (ESI+) 553.2
