Procedure

A suspension of 8-bromo-N-(2-chloro-5-(3-hydroxyazetidine-1-carbonyl)phenyl)-N-methyl-4,5-dihydrobenzo[b]thieno[2,3-d]oxepine-2-carboxamide (400 mg, 0.73 mmol), Pd(OAc)2 (8 mg, 0.037 mmol), Xantphos (42 mg, 0.073 mmol), MeSO2(CH2)2NH2.HCl (175 mg, 1.095 mmol) and Na2CO3 (232 mg, 2.19 mmol) in toluene (5 mL) and DMF (5 mL) was heated at 80° C. under atmosphere of CO from balloon for overnight. Then it was filtrated and concentrated, the crude product was purified by flash column chromatography on silica gel (DCM: MeOH=20:1 as eluted solvent) to give a white solid which was washed with MeOH and dried to give 384 (206.7 mg, yield 46%). 1H NMR (DMSO, 400 MHz): δ8.74 (t, J=5.6 Hz, 1H, NH), 7.87-6.61 (m, 7H, ArH), 5.75 (d, J=6.0 Hz, 1H, OH), 4.48-2.99 (m, 19H). LC-MS: (ESI, m/z)=618 [M+H]+
