A mixture of 0.202 g (0.455 mmol) of 5-amino-N,N'-didecyl-1,3-benzenedicarboxamide, 0.17 ml (1.8 mmol) of methyl bromoacetate, 0.14 g (1 mmol) of potassium carbonate and 0.15 g (1 mmol) of sodium iodide in 10 ml of acetone and 2 ml of DMF was stirred at reflux for 20 hours. Water was added and the product was extracted with ethyl acetate. The dried extract was concentrated at reduced pressure to an oil which was crystallized from methanol-water to give 0.1608 g (67% yield, mp 108°-109°) of N-[3,5-bis[(decylamino)carbonyl]phenyl]glycine methyl ester.
