実験手順

A solution of 8-bromo-4,5-dihydrobenzo[b]thieno[2,3-d]oxepine-2-carboxylic acid (25.00 g, 76.9 mmol) in SOCl2 (200 mL) was heated at 90-100° C. for 3 h. Concentration of the reaction mixture gave the crude acid chloride. A suspension of the acid chloride in THF (600 mL) was treated with a solution of 4-amino-3-chloro-N,N-dimethylbenzamide (18.23 g, 92.3 mmol) and pyridine (14 mL) in THF (200 mL) at 0° C. The mixture was allowed to reach room temperature and stirred overnight. After concentration, water (200 mL) was added into the mixture. The resulting precipitate was collected by filtration, washed with water and dried to give 8-bromo-N-(2-chloro-4-(dimethylcarbamoyl)phenyl)-4,5-dihydro-benzo[b]thieno[2,3-d]oxepine-2-carboxamide (29.88 g, yield: 77%). ESI-MS: 504.99. 1H NMR (DMSO-d6, 400 MHz): δ10.14 (s, 1H, NH), 7.86 (s, 1H, ArH), 7.67-7.57 (m, 3H, ArH), 7.40-7.25 (m, 3H, ArH), 4.32 (t, J=5.2 Hz, 2H, CH2), 3.21 (t, J=5.2 Hz, 2H, CH2), 2.95 (s, 3H, CH3), 2.92 (s, 3H, CH3).
