Reaction Steps

Add 5-bromo-2-fluoro-1,3-dimethyl-benzene (3.5 g, 17.2 mmol) to dimethylformamide (DMF, 30 mL) at ambient temperature followed by sodium thiomethoxide (1.32 g, 17.9 mmol). Heat at 50° C. for 8 hours and dilute with water (10 mL) and diethyl ether (100 mL). Separate the layers, wash the organics with brine, and dry with magnesium sulfate before concentrating to a residue. Chromatograph the residue on a SiO2 column eluting with diethyl ether (20%) in hexane to give 566 mg (14%) of 5-bromo-1,3-dimethyl-2-methylsulfanyl-benzene.
