Procedure

A solution of 2-(4-(2-chlorophenyl)-1-methyl-5-oxo-4,5-dihydro-1H-1,2,4-triazol-3-yl)-4,5-dihydrobenzo[b]thieno[2,3-d]oxepine-8-carboxylic acid (300 mg, 0.66 mmol) in 10 mL of SOCl2 was heated at 80° C. for 3 h. Concentration gave the crude acid chloride, 2-(4-(2-chlorophenyl)-1-methyl-5-oxo-4,5-dihydro-1H-1,2,4-triazol-3-yl)-4,5-dihydrobenzo[b]thieno[2,3-d]oxepine-8-carbonyl chloride which was slowly added (ca. 312 mg, ca. 0.66 mmol in 10 mL of THF), to a solution of NH3 (saturated solution in THF) and pyridine (0.5 mL) in 5 mL of THF at 0° C. The mixture was stirred at room temperature overnight, Diluted with water, the solids were washed with water and dried in vacuum. The crude product was purified by HPLC separation, gave 160.1 mg of 363, isolated yield: 54%. ESI-MS: 453. 1H NMR (DMSO-d6, 400 MHz): δ 7.98-7.41 (m, 9H, ArH, NH2), 6.49 (s, 1H, ═CH), 4.20 (s, 2H, CH2), 3.49 (s, 3H, CH3), 2.99 (s, 2H, CH2).
