Reaction Steps

To a slurry of 8-(1-Azetidin-3-yl-1H-pyrazol-4-yl)-2-(2-isopropyl-5-methyl-2H-[1,2,4]triazol-3-yl)-4,5-dihydro-6-oxa-3-thia-1-aza-benzo[e]azulene (0.232 g, 0.000519 mol) in methanol (3.0 mL, 0.074 mol) was added N,N-Diisopropylethylamine (0.108 mL, 0.000623 mol) then isobutylene oxide (0.330 mL, 0.0037 mol). The reaction was stirred at room temperature overnight. The solvent was removed in vacuo and purified by reverse-phase HPLC to give 480 (24.3 mg) as a colorless solid.
