Versuchsvorschrift
For this isosorbide-2-acetate is for example firstly nitrated with nitric acid in glacial acetic acid or acetic acid anhydride and subsequently the acetate group is cleaved off with potassium carbonate in methanol. In this process isosorbide-5-nitrate is obtained in an isomerically pure form and in excellent yield (FIG. 1).
