Versuchsvorschrift
A solution of HCl in EtOAc (4M, 20 mL) was slowly added into a solution of tert-butyl 4-(4-chloro-3-(N-methyl-8-(methylcarbamoyl)-4,5-dihydrobenzo[b]thieno[2,3-d]oxepine-2-carboxamido)benzoyl)piperazine-1-carboxylate (390 mg, 0.61 mmol) in EtOAc (5 mL) at 0° C. The mixture was stirred at room temperature for overnight. The solids were filtered and washed with EtOAc, dried to give 333 (250 mg, yield 71%). 1H NMR (MeOD, 400 MHz): δ7.76-7.42 (m, 7H, ArH, NH), 6.90 (s, 1H, ═CH), 4.23-2.89 (m, 19H). LC-MS: (ESI, m/z)=539 [M+H]+, 561 [M+Na]+
