실험 절차

2-hydroxymethyl-8-phenethyl-1,4-dioxa-8-azaspiro[4,5]decane (Compound 1.50 gm, 0.18 mole), Para Toluenesulfonic Acid (PTSA, 3.5 gms) was dissolved in toluene (300 ml) at 28° C. To this was added 18.5 gm of morpholine drop wise with continuous stirring, continued the stirring for 13 hrs at reflux temperature. Toluene was distilled under vacuum to get a semi-solid with brick red color. The yield of the product was 90%.
