Diisopropylethylamine → (1-isopropyl-5-{8-[1-(2-methanesulfonyl-ethyl)-azetidin-3-yl]-4,5-dihydro-6-oxa-3-thia-1-aza-benzo[e]azulen-2-yl}-1H-[1,2,4]triazol-3-yl)-carbamic acid benzyl ester

Reaction Steps

The title compound was prepared by a similar procedure to 2-(2-isopropyl-2H-[1,2,4]triazol-3-yl)-8-[1-(2-methanesulfonyl-ethyl)-azetidin-3-yl]-4,5-dihydro-6-oxa-3-thia-1-aza-benzo[e]azulene using 8-azetidin-3-yl-2-(2-isopropyl-2H-[1,2,4]triazol-3-yl)-4,5-dihydro-6-oxa-3-thia-1-aza-benzo[e]azulene 235 HCl salt and diisopropylethylamine. The reaction mixture was diluted with DCM and water. The organic phase dried (Na2SO4) and concentrated in vacuo. The residue was purified by flash chromatography (SiO2, 0-4% MeOH in DCM) to give (1-Isopropyl-5-{8-[1-(2-methanesulfonyl-ethyl)-azetidin-3-yl]-4,5-dihydro-6-oxa-3-thia-1-aza-benzo[e]azulen-2-yl}-1H-[1,2,4]triazol-3-yl)-carbamic acid benzyl ester (157 mg, 73%).
