실험 절차

Alternatively, a suspension of 8-bromo-N-(2-chlorophenyl)-N-methyl-4,5-dihydrobenzo[b]thieno[2,3-d]oxepine-2-carboxamide 150 (113 mg, 0.25 mmol), Mo(CO)6 (66 mg, 0.25 mmol), Hermann's palladacycle (trans-di(mu-acetato)bis[o-(di-o-tolylphosphino)benzyl]dipalladium (II), 23 mg) and tri-tert-butylphosphonium tetrafluoroborate (15 mg) in methanol (0.8 mL) and THF (0.8 mL) in a 10 mL microwave vial was treated with DBU (0.11 mL, 0.75 mmol) and immediately sealed. The whole was heated in a microwave at 110° C. for 20 min, cooled to room temperature and diluted with ethylacetate. The crude suspension was filtered through celite and the eluent concentrated to give a residue that was purified by flash column chromatography (10-100% ethylacetate in hexanes) to give 138 as a colorless solid. 1H NMR (500 MHz, DMSO-d6) δ 7.69-7.49 (m, 7H), 6.57 (m, 1H), 4.22 (m, 2H), 3.85 (s, 3H), 3.23 (s, 3H, obstructed by water), 3.02 (m, 2H). MS: (ESI+) 428.1
