Reaction Steps

A mixture of 8-bromo-2-(2-isopropyl-5-methyl-2H-[1,2,4]triazol-3-yl)-4,5-dihydro-6-oxa-3-thia-1-aza-benzo[e]azulene (0.220 g, 0.000543 mol), tributyl-ethoxyvinyl-tin (0.202 mL, 0.000597 mol), and bis(triphenylphosphine)palladium(II) chloride (0.0190 g, 0.0271 mmol) was degassed with N2. The reaction was heated to 100° C. overnight. The crude was hydrolyzed with 10% HCl and extracted 3 times with ethyl acetate. The organic layers were combined, dried with MgSO4 and concentrated. The crude was loaded as a solid onto silica and purified by flash chromatography (45-100% ethyl acetate in hexanes) to give 1-[2-(2-Isopropyl-5-methyl-2H-[1,2,4]triazol-3-yl)-4,5-dihydro-6-oxa-3-thia-1-aza-benzo[e]azulen-8-yl]-ethanone as a white solid (126 mg). MS(ESI+) 369.2
