Versuchsvorschrift
8-(3-fluoro-pyridin-2-yl)-2,3-dioxa-8-azaspiro[4.5]decane 17 (347 g, 1.456 Mol) was dissolved in acetic acid (700 mL) and water (140 mL) and the mixture heated to 85° C. under nitrogen for 18 h. LC/MS shows the reaction at 92% conversion at this stage. The mixture was evaporated to dryness in vacuo, to leave orange oil. This material was used directly in the next step without further purification
