Procedure

A suspension of 8-bromo-N-(2-chloro-5-((2-hydroxyethyl)(methyl)carbamoyl)phenyl)-N-methyl-4,5-dihydrobenzo[b]thieno[2,3-d]oxepine-2-carboxamide (400 mg, 0.76 mmol), Pd(OAc)2 (10 mg, 0.045 mmol), Xantphos (44 mg, 0.076 mmol), MeNH2.HCl (77 mg, 1.14 mmol) and Na2CO3 (242 mg, 2.28 mmol) in toluene (5 mL) was heated at 80° C. under atmosphere of CO from balloon overnight. Then it was filtrated and concentrated, the crude product was purified by column (EtOAc: MeOH=10:1) to afford 383 (87.2 mg, yield: 22%). 1HNMR (DMSO-d6, 400 MHz): δ8.45 (d, J=4.4 Hz, 1H), 7.72-7.43 (m, 6H), 6.73 (s, 1H), 4.89-4.76 (m, 1H), 4.20-4.04 (m, 2H), 3.60-2.66 (m, 15H). LC-MS: (ESI, m/z)=528 [M+H]+
