Ethanethiol → (4-Bromo-3-chlorophenyl)(ethyl)sulfane

To a solution of 1-bromo-2-chloro-4-fluorobenzene (24.8 g, 119 mmol) and ethanethiol (10.6 mL, 143 mmol) in N,N-dimethylformamide (150 mL) was added sodium hydride (60% in oil, 6.00 g, 150 mmol) at room temperature by small portions, and the resulting mixture was stirred for 4 hr. The reaction mixture was diluted with ethyl acetate, washed twice with water and once with saturated brine, dried over anhydrous magnesium sulfate and concentrated under reduced pressure. The residue was purified by silica gel column chromatography (hexane) to give the title compound (19.4 g, yield 65%) as a colorless oil.
