Procedure

Potassium carbonate (5.0 g, 36.2 mmol) and 1-propanethiol (2.7 g, 35.5 mmol) were added to a N-methylpyrolidone (NMP) solution (15 ml) of 2,5-difluoronitrobenzene (5.0 g, 31.4 mmol), and the mixture obtained was stirred at 90° C. for 2 hours. After the reaction mixture was cooled to room temperature, water (50 ml) was added, and the reaction product was extracted with ethyl acetate (100 ml). The organic layer was washed with water, and then dried over anhydrous magnesium sulfate. The resulting dry product was concentrated under reduced pressure to thereby obtain 6.7 g of powdery yellow 4-fluoro-2-nitro-1-propylsulfanylbenzene (yield: 99%).
