Procedure

A suspension of 2-(3-(8-bromo-N-methyl-4,5-dihydrobenzo[b]thieno[2,3-d]oxepine-2-carboxamido)-4-chlorobenzamido)ethyl acetate (400 mg, 0.69 mmol), Pd(OAc)2 (10 mg, 0.045 mmol), Xantphos (40 mg, 0.069 mmol), MeNH2.HCl (70 mg, 1.04 mmol) and Na2CO3 (219 mg, 2.07 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 dissolved in 10 mL of THF/H2O=1:1. 0.14 g of NaOH was added. The mixture was stirred at room temperature for overnight. The mixture was extracted by DCM and purified by column (EtOAc: MeOH=10:1) to afford 431 (72.6 mg, yield: 20%) 1H NMR (DMSO-d6, 400 MHz): δ8.62 (t, J=5.6 Hz, 1H), 8.41 (d, J=4.8 Hz, 1 H), 8.07 (s, 1H), 7.95 (d, J=7.6 Hz, 1H), 7.74 (d, J=8.4 Hz, 1H), 7.46 (s, 2H), 7.39 (s, 1H), 6.58 (s, 1H), 4.73 (t, J=5.6 Hz, 1H), 4.16 (s, 2H), 3.50 (dd, J=6.0, 10.0 Hz, 2H), 3.31-3.27 (m, 5H), 2.94 (s, 2H), 2.72 (d, J=4.4 Hz, 3H). LC-MS: (ESI, m/z)=514 [M+H]+
