Procedure
To a solution of 15.8 g (0.086 mol) 2,2-dimethyl-6,6-diethyl-4-oxopiperidine in 50 ml methanol 2.2 g (0.06 M) sodium borohydride are added in portions. The temperature is kept below 30° C. After stirring over night methanol is removed under vacuum and the residue is diluted with 20 ml 2N-NaOH. The solution is extracted with ethylacetate. The combined extracts are washed with saturated NaCl solution, dried over MgSO4 and dried under vacuum at 60° C./50 mbar until a constant weight is achieved. 15.8 g (99%) 2,2-dimethyl-6,6-diethyl-4-hydroxypiperidine are obtained as yellowish oil.
