Anthranilic Acid → HCID 21832992, compound

Participants

Reaction Steps

Triethylamine (1.76 ml) was added to a suspension of anthranilic acid (823 mg) in methylene chloride (20 ml). Then, myristoyl chloride (1.63 ml) was dropwise added to the mixture while being cooled with ice. After being stirred for 2.5 hour at room temperature, the reaction mixture was cooled with ice. Triethylamine (0.92 ml) and ethyl chlorocarbonate (0.63 ml) were dropwise added to the reaction mixture successively. After being stirred for 1 hour at 0° C. and for 1.5 hours at room temperature successively, the reaction mixture was concentrated. The residue, with ethyl acetate added thereto, was washed with water, neutralized with diluted hydrochloric acid, and washed with saturated brine. The organic layer was dried over magnesium sulfate anhydride and then concentrated. The residue was purified by silica gel column chromatography (silica gel 60 g, chloroform-hexane), thereby yielding 1.663 g of the aimed compound as colorless crystals.
