Procedure

A suspension of 8-bromo-N-(2-chloro-5-(3,3-difluoroazetidine-1-carbonyl)phenyl)-N-methyl-4,5-dihydrobenzo[b]thieno[2,3-d]oxepine-2-carboxamide (400 mg, 0.70 mmol), Pd(OAc)2 (8 mg, 0.035 mmol), Xantphos (41 mg, 0.070 mmol), MeSO2(CH2)2NH2.HCl (169 mg, 1.06 mmol) and Na2CO3 (224 mg, 2.11 mmol) in toluene (5 mL) and DMF (5 mL) was heated at 80° C. under atmosphere of CO from balloon for 3 h. Then it was filtrated and concentrated, the crude product was purified by flash column chromatography on silica gel (petroleum ether: EtOAc=2:1-1:5 as eluted solvent) to give a white solid which was washed with DCM and dried to give 432 (121.3 mg, yield: 27%). 1H NMR (DMSO-d6, 400 MHz): δ 8.73-6.60 (m, 8H, NH, ArH), 4.75-3.02 (m, 18H). LC-MS: (ESI, m/z)=638 [M+H]+
