Procedure
Under an atmosphere of nitrogen, 53 mg (0.20 mmol) of 4-(2-naphtyloxy) benzoic acid was suspended in 5 ml of dried methylene chloride, to which were added 56 mg (0.44 mmol) of oxyalyl chloride and then 1 drop of DMF with a pipette. The mixture was stirred at 35° C. for 1.5 hours. The reaction mixture was concentrated with an evaporator, and the residue was dissolved in 5 ml of dried methylene chloride. Under an atmosphere of nitrogen, the solution, while being cooled with ice, was added dropwise to a solution of 19 mg (0.20 mmol) of aniline and of 22 mg (0.22 mmol) of triethyl amine in dried methylene chloride (5 ml), and the resulting mixture was stirred for 4 hours in an ice bath, and then stirred overnight at room temperature. Water was added to the reaction mixture, and extracted with methylene chloride twice. The organic phase was washed with brine dried with anhydrous sodium sulfate, and the solvent was removed by evaporation. The residue was purified by silica gel column chromatography (hexane:ethyl acetate=20:1) to give 27 mg (40% yield) of N-phenyl-(4-(2-naphthyloxy)benzamide). White solid.
