4-Carbamoylphenyl 2-(2-(2,6-dichlorophenylamino)phenyl)acetate (5, 480 mg, 1.14 mmol) and Lawesson reagent (460 mg, 1.14 mmol) were dissolved in 20 ml of anhydrous benzene. The reaction was warmed to 50° C. and stirred for 6 h. The solvent was removed under reduced pressure; the crude residue was purified by silica gel column (dichloromethane/methyl alcohol 9.5/0.5) to furnish the pure compound 6 (446 mg, 91% yield).
