Procedure

To a solution of 1,2-difluoro-4,5-dimethoxybenzene (2.61 g, 15 mmol) in N,N-dimethylformamide (20 ml) was added sodium thiomethoxide (95%, 1.11 g, 15 mmol). The reaction was allowed to reflux for 3 hours and then was cooled to room temperature. The mixture was poured into 200 ml ice-water and neutralized with 2 N HCl. The aqueous layer was extracted with ethyl ether (2×100 ml), washed with water, dried over anhydrous sodium sulfate and filtered. The solvent was removed under vacuum to afford a mixture of the two title products.
