Procedure

Following the procedures for 246, 9-Chloro-2-[2-(2,4-difluoro-phenyl)-2H-[1,2,4]triazol-3-yl]-4,5-dihydro-6-oxa-1-thia-10-aza-benzo[e]azulene and but-3-yn-1-ol were reacted under palladium catalysis to give 4-{2-[2-(2,4-Difluoro-phenyl)-2H-[1,2,4]triazol-3-yl]-4,5-dihydro-6-oxa-1-thia-10-aza-benzo[e]azulen-9-yl}-but-3-yn-1-ol (Yield: 81%. 1H NMR (DMSO-d6, 400 MHz): δ8.31 (s, 1H), 7.94-7.88 (m, 1H), 7.74-7.68 (m, 1H), 7.43-7.38 (m, 2H), 7.31 (d, J=8.4 Hz, 1H), 6.92 (s, 1H), 4.95 (s, 1H), 4.31 (t, J=4.0 Hz, 2H), 3.62 (m, 2H), 3.12 (t, J=4.4 Hz, 2H), 2.61 (t, J=6.8 Hz, 2H). LC-MS (ESI): m/z=451 [M+H]+), which was hydrogenated to give 245 Yield: 43%. 1H NMR (DMSO-d6, 400 MHz): δ8.27 (s, 1H), 7.90-7.84 (m, 1H), 7.70-7.65 (m, 1H), 7.41-7.39 (m, 1H), 7.29 (d, J=8.4 Hz, 1H), 7.06 (d, J=8.4 Hz, 1H), 6.99 (s, 1H), 4.37 (s, 1H), 4.23 (t, J=4.8 Hz, 2H), 3.40 (t, J=6.4 Hz, 2H), 3.09 (t, J=4.8 Hz, 2H), 2.64-2.60 (m, 2H), 1.65-1.59 (m, 1H), 1.44-1.38 (m, 1H). LC-MS (ESI): m/z=455 [M+H]+
