Reaction Steps

A mixture of 1.37 g. of 4-aminobenzoic acid, 3.50 g. of methyl 16-bromohexadecanoate, 2.12 g. of sodium carbonate and 140 ml. of hexamethylphosphoramide is stirred at 120° C. for 18 hours, allowed to cool, and poured into dilute hydrochloric acid. The precipitate is collected by filtration, dried, and crystallized from acetonitrile to yield 4-(15-carbomethoxypentadecylamino)benzoic acid as a white solid.
