Procedure
6N hydrochloric acid (7 ml) was added to (8-cyclohexyl-1,4-dioxa-spiro[4.5]dec-8-yl)-dimethyl-amine (C-5) (1.18 g, 4.41 mmol), and the mixture was stirred overnight at room temperature. When the hydrolysis was complete, the reaction mixture was extracted with ether (2×10 ml), the aqueous solution was rendered alkaline with 5N sodium hydroxide solution, while cooling with ice, the reaction mixture was extracted with dichloromethane (3×20 ml), and the organic phase was dried over sodium sulfate and concentrated in vacuo. The crude product (637 mg) was purified by flash chromatography with CHCl3/MeOH (9:1).
