Reaction Steps
4-Cyano-4-phenylpiperidine (1.1 g, 0.0059 mol) and 2,3-epoxypropyl-n-hexadecylether (1.6 g, 0.0056 mol) were combined and heated to 185° C. for 30 minutes. After cooling, ethyl acetate (20 ml) and acetonitrile (20 ml) were added, and the resulting solid was collected by filtration (1.6 g, 62% yield): mp 69°-70° C.; ir (KBr) 2227 cm-1.
