実験手順

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 (500 mg, 0.91 mmol), Pd(OAc)2 (10 mg, 0.046 mmol), Xantphos (53 mg, 0.091 mmol), MeNH2.HCl (92 mg, 1.37 mmol) and Na2CO3 (289 mg, 2.73 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 360 (221.5 mg, yield 46%). 1H NMR (DMSO, 400 MHz): δ8.43 (m, 1H, NH), 7.87-7.43 (m, 6H, ArH), 6.65 (s, 1H, ═CH), 5.52 (d, J=6.4 Hz, 1H, OH), 4.48-2.75 (m, 15H). LC-MS: (ESI, m/z)=526 [M+H]+
