실험 절차
A solution of 10 g. of 14-methylpentadecyl bromide and 10.8 g. of ethyl 4-aminobenzoate in 75 ml. hexamethylphosphoramide is heated at 120° C. for 17 hours. The cooled solution is diluted with 100 ml. water, filtered, and the residue is washed with 100 ml. 50% ethanol-water. The product is dried, then crystallized from ethanol to yield ethyl 4-(14-methylpentadecyl)aminobenzoate as colorless crystals.
