Procedure

Sodium methanethiolate (1.22 g; 17.4 mmol) was added in three portions to a stirred solution of 1-(chloromethyl)-3-fluoro-5-nitrobenzene (3.00 g; 15.8 mmol, HE Chemical) in ethanol (33 mL) at 0° C. The ice bath was removed and the batch was stirred at room temperature for 18 hours. Further sodium methanethiolate (0.33 g; 4.7 mmol) was added and the batch was stirred for 5 additional hours at room temperature. The batch was diluted with brine and extracted with ethyl acetate (2×). The combined organic phases were washed with water, dried (sodium sulfate), filtered and concentrated to give the desired product (3.4 g) that was used without further purification.
