Procedure

To a stirred solution of 20 g of ethyl 2-[(hexadecyloxy)methyl]-2-propenoate in 60 ml of ethyl alcohol containing 10 ml of triethylamine is added 53 ml hexadecylmercaptan. Following stirring for 18 hours, the volatile components are removed and the residue is chromatographed by HPLC on silica gel using 9:1 hexanes:ethyl acetate. Fractions containing product are combined and the solvents evaporated to give 32.9 g of the desired product as a white waxy solid.
