Reaction Conditions

Reaction Steps

Triethylamine (1.58 ml) was added to a suspension of behenic acid (3.51 g) in methylene chloride (35 ml). Then, ethyl chlorocarbonate (1.08 ml) was dropwise added to the mixture while being cooled with ice. After being stirred for 1.5 hours at 0° C., the mixture, with a mixed solution of anthranilic acid (1.42 g) and triethylamine (1.44 ml) in methylene chloride (7 ml) dropwise added thereto, was stirred for 3 hour at 0° C. and for 15 hours at room temperature successively, and then cooled with ice. The reaction mixture, with triethylamine (1.58 ml) and ethyl chlorocarbonate (1.08 ml) dropwise added thereto, was stirred for 1 hour at 0° C. and for 2.5 hours at room temperature successively, and then concentrated. The residue, with chloroform added thereto, was washed with water and saturated brine successively. The organic layer was dried over sodium sulfate anhydride, and then concentrated. The residue was purified by silica gel column chromatography (silica gel 100 g, hexane-chloroform), thereby yielding 3.39 g of the aimed compound as colorless solid.
