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, from the procedure for 249, (470 mg, 1.0 mmol), Piperidine (102 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 232 (46.2 mg, yield: 8.5%). 1HNMR (DMSO-d6, 400 MHz): δ8.74 (s, 1H), 8.31 (s, 1H), 8.10 (d, J=4.8 Hz, 1H), 7.91-7.87 (m, 1H), 7.78-7.77 (m, 2H), 7.50-7.40 (m, 1H), 7.18 (d, J=4.4 Hz, 1H), 7.19 (d, J=8.8 Hz, 1H), 6.93 (d, J=8.8 Hz, 1H), 4.31 (s, 2H), 3.64 (s, 4H), 3.16 (s, 2H), 1.63-1.57 (m, 4H) ESI-MS: m/z=543 [M+H+]
