2-(8-Methyl-1,4,7,9-tetraoxaspiro[4.5]dec-8-yl)ethanol → 2-(((3-Methyl-4-(2-(8-methyl-1,4,7,9-tetraoxaspiro[4.5]dec-8-yl)ethoxy)pyridin-2-yl)methyl)sulfinyl)-6,7-dihydro-1h-[1,4]dioxino[2,3-f]benzimidazole sodium salt

Participants

Reaction Steps

The same procedure as in the steps (5d) to (5h) was repeated using the 2-(8-methyl-1,4,7,9-tetraoxaspiro[4.5]dec-8-yl)ethanol and 6,7-dihydro-1H-[1,4]dioxino[2′,3′:4,5]benzo[d]imidazole-2-thiol obtained in Example (73b) to obtain the title compound (110 mg, content: 93.5%, total 9.2% yield) as a white solid.
