Versuchsvorschrift

The mixture of 8-bromo-N-(2-chloro-4-(dimethylcarbamoyl)phenyl)-N-methyl-4,5-dihydrobenzo[b]thieno[2,3-d]oxepine-2-carboxamide (27.0 g, 51.9 mmol), dppf (23.20 g, 41.9 mmol), Pd(OAc)2 (5.8 g, 25.8 mmol), TEA (27 mL), in DMF (270 mL) and MeOH (400 mL) was stirred under CO (50 psi) atmosphere at 70° C. for 2 days. The reaction mixture was filtrated and the filtrate was concentrated. The crude product was purified by silica gel chromatography eluted with Hexanes: EtOAc=1:1 to give methyl 2-((2-chloro-4-(dimethylcarbamoyl)phenyl)(methyl)-carbamoyl)-4,5-dihydrobenzo[b]thieno[2,3-d]oxepine-8-carboxylate (23.00 g, 89%). ESI-MS: 499.1. 1H NMR (DMSO-d6, 400 MHz): δ7.74-7.69 (m, 2H, ArH), 7.58-7.47 (m, 4H, ArH), 6.79 (s, 1H, ═CH), 4.23 (t, J=4.8 Hz, 2H, CH2), 3.83 (s, 3H, CH3), 3.31 (s, 3H, CH3), 3.01 (br, 5H, CH2, CH3), 2.94 (s, 3H, CH3).
