Procedure

To a solution of 2-(4-(2-chlorophenyl)-4H-1,2,4-triazol-3-yl)-4,5-dihydro-benzo[b]thieno[2,3-d]oxepin-8-amine HCl salt (0.2 g, 0.464 mmol) in 10 ml of dried DCM was added TEA (0.32 mL, 2.3 mmol). The mixture was stirred at 0° C. for 20 min and 0.2 ml of methyl chloroformate was added. The reaction mixture was stirred for 10 min and the solution was quenched with water and evaporated to the crude product, which was purified by preparative HPLC to give 113 (81 mg, 38%). 1HNMR (DMSO-d6, 400 MHz): δ 9.78 (s, 1H), 8.81 (s, 1H), 7.79-7.12 (m, 7H), 6.53 (s, 1H), 4.15 (t, J=5.2 Hz, 2H), 3.63 (s, 3H), 2.93 (t, J=5.2 Hz, 2H). MS: (ESI+) 453.1
