実験手順

A mixture of 3.25 g (7.74 mmol) of 3-amino-5-(octadecyloxy)benzoic acid methyl ester, 3.7 ml (23 mmol) of benzyl bromoacetate, 4.2 g (19.4 mmol) of 1,8-bis(dimethylamino)naphthalene and 0.3 g (2.2 mmol) of sodium iodide in 65 ml of acetronitrile and 20 ml of DMF was stirred and heated at reflux under argon for 48 hours. The reaction mixture was concentrated at reduced pressure and ethyl acetate was added to the residue. The extract was washed with 0.05N HCl, with saturated NaHCO3 solution, dried and concentrated at reduced pressure to a solid which was purified by HPLC using 15% ethyl acetate-hexane to give 2.6 g (48% yield, mp 62°-63°) of N-[3-(methoxycarbonyl)-5-(octadecyloxy)phenyl]-N-[2-oxo-2-(phenylmethoxy)ethyl]glycine phenylmethyl ester.
