Procedure

To a solution of N-(4-phenoxy-phenyl)-acetamide (1.20 g, 5.28 mmol) in 10 ml of toluene was added Lawesson's reagent (1.50 g, 3.70 mmol). The reaction mixture was heated at 120° C. for 2 h. After the completion of the reaction (TLC monitoring), the reaction mixture was evaporated to dryness under reduced pressure. The residue was purified by column chromatography on silica (60-120 M) using ethyl acetate/hexane (5:95) as the eluent to provide the title compound (0.78 g, 60.7%).
