Reaction Steps
A 6 g. (16.6 m moles) sample of 4-(hexadecylamino)-benzoic acid and 2.7 g. (16.6 m moles) 1,1'-carbonyldiimidazole in 50 ml. dry tetrahydrofuran is stirred for 2 hours. Then, 1.58 g. (16.6 m moles) 3-hydroxypyridine and a trace of sodium hydride catalyst is added and the reaction is refluxed for 3 hours. The solution is cooled, filtered, and evaporated. The product is crystallized from isopropanol.
