반응 단계
Under ambient conditions a sealable reaction vessel was charged with 8-bromo-N-(2-chlorophenyl)-N-(2-hydroxyethyl)-4,5-dihydrobenzo[b]thieno[2,3-d]oxepine-2-carboxamide (0.08 g, 0.17 mmol), molybdenum hexacarbonyl (0.044 g, 0.167 mmol) in methanol (0.5 ml, 10 mmol)/THF 1 ml, 10 mmol), followed by the addition of 2M methylamine in THF (0.251 ml),/trans-D(mu-acetato)bis[di-o-tolylphosphino)benzyl]dipalladium(II) (32.3 mg, 0.0334 mmol). Finally, DBU (0.025 ml, 0.167 mmol) was added and the reaction vial was quickly sealed. The charged reaction vial was flash heated on a Biotage Emrys Optimizer microwave at 150° C. for 20 minutes. The cooled reaction mixture was diluted with ethyl acetate and filtered through a bed of Celite. The filtrate was concentrated to a solid and purified by MPLC on silica to give 3.2 mg 154 (yield=4.3% of theoretical). MS: (ESI+) 458.2
