Procedure

Sodium 3-piperidinopropanolate (5 mmol), 5 mmol of 3,3-dimethylbutyl chloride, a catalytic amount of tetrabutylammonium iodide, and 0.5 mmol of 15-crown-5 in 10 ml of dry dimethyl sulfoxide were refluxed for 12 hours. Water was added, and it was extracted with diethyl ether. The organic layer was purified by column chromatography on silica gel (eluent: methylene chloride/methanol (90/10), ammonia atmosphere). The solvent was removed under reduced pressure and the residue crystallized with oxalic acid from diethyl ether/ethanol.
