Procedure
47.9 g (250 mmol) of 2-chloro-4-fluoro-5-nitrophenol, 34.6 g (250 mmol) of potassium carbonate, 1 g of potassium iodide and 58.5 g (300 mmol) of 3-bromomethyltetrahydrothiopyran in 500 ml of acetonitrile were refluxed for 5 hours. The mixture was cooled to 25° C. and filtered, the solvent was removed from the filtrate, the residue was taken up in methylene chloride, and the solution was washed with water, dried and concentrated. 22 g (29%) of 2-chloro-4-fluoro-5-nitro-1-(3-tetrahydrothiopyranylmethoxy)benzene (melting point 100° to 103° C.) were obtained.
