实验步骤: To a solution of about 34.35 g of isopropylcyclohexylamine in about 150 ml of tetrahydrofuran at about -20° C. was added about 156.89 ml of an about 1.55M n-butyllithium, at a rate so that the final temperature reached about 10° C. The solution was then cooled to about -70° C. and about 25 g of ethyl levulinate ethylene ketal was added dropwise. After about 15 minutes, the solution was warmed to about -30° C. and maintained at that temperature while it was added rapidly, dropwise to a stirred solution of about 80.44 g of octadecyl iodide in about 150 ml of dimethyl sulfoxide and about 50 ml of tetrahydrofuran at room temperature. This mixture was stirred overnight, the volatile solvents were removed and water was added. The resulting solid was collected by filtration and extracted with ether giving a solution and a solid. This solution and original filtrate were combined and extracted with ether. This ether extract was dried and the solvent removed giving an oil. This oil was subjected to HPLC, eluting with hexane:ether (about 9:1). The product band was collected and the solvent removed, giving about 30.76 g of the desired title compound as a solid, mp 33°-34° C. reached about 10° C the solution was warmed to about -30° C. maintained at that temperature while it the volatile solvents were removed water was added The resulting solid was collected by filtration extracted with ether giving a solution extracted with ether This ether extract was dried the solvent removed giving an oil eluting with hexane The product band was collected the solvent removed

An about 187.88 g portion of octadecyl iodide and about 150 ml of tetrahydrofuran were added and the thick mixture was stirred with a glass rod, and then with magnetic stirring for about 3 hours. Water was then added and the mixture was extracted with ether. The ether extract was washed with brine, dried and filtered through a pad of florisil. The solvent was removed and the residue chromatographed on florisil, eluting first with petroleum ether, then with about 10% ether in petroleum ether and finally eluting the product with about 30% ether in petroleum ether, giving about 73.3 g of the desired title compound as a waxy solid. the thick mixture was stirred with a glass rod with magnetic stirring for about 3 hours the mixture was extracted with ether The ether extract was washed with brine dried filtered through a pad of florisil The solvent was removed the residue chromatographed on florisil eluting first with petroleum ether with about 10% ether in petroleum ether and finally eluting the product with about 30% ether in petroleum ether
