실험 절차
The oxime of 2,2 dimethylcyclopentanone is prepared by reaction of the ketone with hydroxylamine hydrochloride in EtOH, and treated with p-toluenesulfonyl chloride and DMAP. Heating then effects Beckmann rearrangement to give 6,6-dimethyl-2-piperidinone which is deprotonated with NaH in DMF solution. Reaction with n-butyl iodide then gives the title compound.
