Reaction Steps
To a stirred solution of 1-bromo-4-fluoro-2-methoxybenzene (10.0 g) in DMF (100 mL) was added sodium methanethiolate (4.44 g). The mixture was stirred at 65° C. for 2 h. The mixture was cooled to 0° C. and methyl iodide (4.55 mL) was added. The mixture was stirred at room temperature for 1 h and further sodium methanethiolate (4.44 g) was added. The mixture was stirred at 65° C. for 1 h. The mixture was cooled to 0° C. and methyl iodide (4.55 mL) was added. The mixture was stirred at room temperature for 1 h. Water was added and the mixture was extracted with ethyl acetate. The organic phase was washed with saturated sodium chloride solution, dried (sodium sulfate) and the solvent was removed in vacuum. Silica gel chromatography gave 6.2 g of the title compound as a 2:1 mixture with the starting material. The mixture was used for the next step without purification.
