Procedimiento

40% aqueous dimethylamine solution (85 ml, 0.67 mol), 1,4-dioxa-spiro-[4.5]decane-8-carbaldehyde (240 g, 0.141 mol) and potassium cyanide (22.05 g, 0.338 mol) were added, while cooling with ice, to a mixture of 4 N hydrochloric acid (37 ml) and methanol (22 ml). The mixture was stirred for 4 d at room temperature; water (80 ml) was added and then the mixture was extracted with diethyl ether (4×100 ml). The organic phase was dried over sodium sulfate and concentrated in vacuo, and the product was obtained in the form of a white solid.
