Procedure

A mixture of 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 (0.36 g, 0.92 mmol), methyl vinyl sulfone (0.24 mL, 2.8 mmol), bis(triphenylphosphine)palladium(II) chloride (64 mg, 0.092 mmol) and triethylamine (0.64 mL, 4.6 mmol) in DMF (10 mL) was heated under an argon atmosphere for 16 h. The reaction mixture was concentrated and purified by column chromatography (40 g column, 0-100% EtOAc/heptane) to provide 280 mg (73% yield) of 143. LC/MS (ESI+): m/z 417 (M+H). 1H NMR (400 MHz, DMSO) δ 8.59 (d, J=2.0, 1H), 8.11 (s, 1H), 7.71 (dd, J=8.4, 2.1, 1H), 7.59-7.26 (m, 2H), 7.17 (d, J=8.4, 1H), 5.88-5.67 (m, 1H), 4.43 (t, J=4.8, 2H), 3.48 (dd, J=12.3, 7.5, 2H), 3.12 (s, 1H), 1.58 (d, J=6.6, 6H)
