Procedure
4-(1,4-Dioxaspiro[4.5]decan-8-yloxy)pyridine (1.6 g, 6.808 mmol, 1.0 eq.) was dissolved in MeOH (16 ml). 6 M HCl solution (16 ml) was added at 0° C. to the solution and the mixture was then stirred for 16 hours at RT. After monitoring by TLC, the solvent was removed under reduced pressure and the residue was taken up in water (50 ml), adjusted to pH 9 with NaHCO3 solution and extracted with DCM (2×75 ml). The combined org. phases were washed with water and sat. NaCl solution (in each case 100 ml), dried over sodium sulfate and concentrated under reduced pressure and dried. The crude product was used in the next stage without being purified further. Yield: 89% (1.15 g, 6.052 mmol)
