Procedure

2-[2-(2,4-Difluoro-phenyl)-2H-[1,2,4]triazol-3-yl]-9-(6-fluoro-pyridin-3-yl)-4,5-dihydro-6-oxa-1-thia-10-aza-benzo[e]azulene (470 mg, 1.0 mmol), from the procedure for 249, 2-Methoxy-ethylamine (90 mg, 1.2 mmol), DIPEA (340 mg, 3 mmol) and NMP (4 mL) were added in a 10 mL of sealed tube, and the mixture was heated by microwave at 150° C. for 120 min under N2. The reaction mixture was filtered to gather the solution and water was added. The mixture was extracted by DCM (20 mL×3). The combined organic layers were dried over Na2SO4, concentrated in vacuo, and purified by preparative HPLC to give 341 (105.5 mg, yield: 20%). 1HNMR (DMSO-d6, 400 MHz): δ8.63 (s, 1H), 8.31 (s, 1H), 7.94-7.88 (m, 2H), 7.76-7.68 (m, 2H), 7.46-7.38 (m, 2H), 7.21 (s, 2H), 6.99 (s, 1H), 6.63 (d, J=8.8 Hz, 1H), 4.31 (s, 2H), 3.49 (s, 4H), 3.29 (s, 3H), 3.15 (s, 2H). ESI-MS: m/z=533 [M+H+]
