Procedure

A solution of 10 g. of 14-hydroxytetradecyl bromide and 10.8 g. of ethyl 1-(4-aminobenzoyl)pyrrolidine in 75 ml. hexamethylphosphoramide is heated at 110° C. for 17 hours. The cooled solution is diluted with 100 ml. water, filtered, and the residue is washed in portions with 100 ml. 50% ethanol-water. After drying the product is crystallized from ethanol to yield 1-[4-(14-hydroxytetradecylamino)benzoyl]pyrrolidine as a white solid.
