9-Bromo-2-(2-isopropyl-2H-[1,2,4]triazol-3-yl)-4,5-dihydro-6-oxa-3-thia-1-aza-benzo[e]azulene from Example 6 and 1-(phenylsulfonyl)-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-1H-pyrazole were reacted under palladium Suzuki conditions to give 301 (39% yield). LC/MS (ESI+): m/z 519 (M+H). 1H NMR (400 MHz, DMSO) δ 8.85 (s, 1H), 8.62 (d, J=2.1, 1H), 8.28 (s, 1H), 8.11 (s, 1H), 8.03 (d, J=7.6, 2H), 7.81 (t, J=7.5, 1H), 7.75-7.60 (m, 3H), 7.12 (d, J=8.4, 1H), 5.82 (dt, J=13.0, 6.6, 1H), 4.39 (t, J=4.8, 2H), 3.46 (t, J=4.9, 2H), 1.59 (d, J=6.6, 6H)
