Reaction Conditions

Reaction Steps

Triethylamine (0.44 ml) and diphenylphosphinic chloride (0.48 ml) were added to a suspension of 2-(octadecanoylamino)benzoic acid (0.85 g) in methylene chloride (10 ml). After being stirred for 3 hours at 0° C., the mixture, with N,N-dimethyl-1,3-propanediamine (0.33 ml) added thereto, was stirred for 44 hours at room temperature. The reaction mixture was then diluted with chloroform, washed with saturated sodium hydrogencarbonate aqueous solution and water successively, dried over sodium sulfate anhydride, and concentrated. The residue was purified by silica gel column chromatography (silica gel 20 g, chloroform-methanol), thereby yielding 0.53 g of N-{2-{N-{3-(dimethylamino)propyl}carbamoyl}phenyl}octadecaneamide and 0.37 g of the aimed compound as colorless crystals.
