실험 절차

17.4 g (123.6 mmol) of 4-tert-butylpiperidine, 9.0 g (30.9 mmol) of 8-tert-butyl-2-bromomethyl-1,4-dioxaspiro[4,5]decane (cis/trans mixture) and 4.3 g (30.9 mmol) of potassium carbonate in 100 ml of absolute dimethylformamide were heated at 150° C. for 8 hours. Some of the solvent was distilled off under reduced pressure, the residue was taken up with dilute aqueous sodium hydroxide solution/methylene chloride and the solution was worked up in a conventional manner.
