실험 절차

N-Benzyl-N-methyl-1,4-dioxaspiro[4.5]decan-8-amine (1.0 g, 3.83 mmol, 1.0 eq.) was dissolved in MeOH (12 ml); 6 M HCl solution (12 ml) was added at 0° C., and stirring was carried out 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 8-9 with NaCHO3 (solid) and extracted with DCM (2×50 ml). The combined org. phases were washed with water and sat. NaCl solution (in each case 50 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: 74% (620 mg, 2.857 mmol)
