Reaktionsschritte

To a mixture of lithium aluminium hydride (831 mg) and anhydrous tetrahydrofuran (70 ml) at 0° C. was added a solution of ethyl 1,4-dioxaspiro[4.5]decane-8-acetate of Example 90 (2) (5.0 g) in anhydrous tetrahydrofuran (30 ml). The mixture was gradually warmed to about 25° C., stirred for 3 hours, and then sodium fluoride, water and dichloromethane were added to the reaction mixture. The precipitate was filtrated off with Celite, the filtrated organic layer was dried over sodium sulfate. The solvent was removed in vacuo from the organic layer to give 4.18 g of 8-(2-hydroxyethyl)-1,4-dioxaspiro[4.5]decane.
