Procedure

A mixture of 3-octadecylthiopropyl chloride (3.53 g., 0.01 mole), diethanolamine (2.1 g., 0.02 mole) and benzyl alcohol (5 ml.) is heated under reflux for one-half hour, then treated with an ethanolic solution of sodium hydroxide (0.4 g., 0.01 mole) and refluxed for five more minutes. The mixture is cooled, filtered, and the ethanol removed by evaporation. The benzyl alcohol is then removed by distillation in vacuo and the residue chromatographed on silica using first ether then methanol as eluants. The desired product is contained in the methanol eluate. It is isolated by evaporation of the solvent, m.p. 53°-54° C. Its hydrochloride salt melts at 65°-66° C.
