A mixture of 1.5 g (2.88 mmol) of N-[3-hydroxy-5-(octadecyloxy)phenyl]-N-(2-methoxy-2-oxoethyl)glycine methyl ester, 1.24 g (2.88 mmol) of 2-(4-chlorobutyl)-6,7-bis(phenylmethoxy) naphthalene, 0.8 g (5.75 mmol) of potassium carbonate and 0.43 g (2.88 mmol) of sodium iodide in 50 ml of acetone and 10 ml of DMF was stirred at reflux under argon for 40 hours. The acetone was removed by distillation and 50 ml of DMF, 1.24 g of 2-(4-chlorobutyl)-6,7-bis(phenylmethoxy)naphthalene, 0.8 g of potassium carbonate and 0.43 g of sodium iodide was added and the mixture was stirred and heated at 85° for 4 days. The DMF was removed using an oil pump at 55°. The residue was extracted with methylene chloride, the extract was concentrated and the product was purified by HPLC using 20% ethyl acetate-hexane to give 1.3 g (49% yield) of N-(2 -methoxy-2-oxoethyl)-N-[3-(octadecyloxy)-5-[4-[2,3-bis(phenylmethoxy)-6-naphthalenyl]butoxy]phenyl]glycine methyl ester as a semisolid. The nmr and mass spectra were consistent with the structure.
