Procedure
A mixture of 2,4-Dichloro nitro benzene (0.25 g, 1.3 mmol), 4-Acetamido thiophenol (0.26 g, 1.43 mmol) and cesium carbonate (0.466 g, 1.43 mmol) in DMF (3 mL) was heated 2.5 hr at 100° C. The mixture was cooled, diluted with ethyl acetate (100 mL) and the organic layer was washed with water and aqueous 10% sodium chloride solution, then, dried over anhydrous sodium sulfate. The drying agent was filtered and the solvent removed under vacuum. The residue is purified by silica gel column chromatography eluting with CH2Cl2/methanol leaving the title compound as a yellow solid (0.25 g, 63%).
