Procedure

To a room temperature solution of 1-bromo-4-fluoro-2-methoxybenzene (5.00 g, 24.39 mmol) in DMF (15 mL) was added sodium ethanethiolate (2.66 g, 31.71 mmol) and the resulting reaction mixture was stirred for 72 hours. The reaction mixture was partitioned between water (20 mL) and EtOAc (50 mL). The organic layer was separated and the aqueous layer was further extracted with EtOAc (3×50 mL). The organic layers were combined and washed with saturated brine solution (20 mL) then dried over Na2SO4, filtered and concentrated in vacuo. The crude material was purified by silica gel column chromatography eluting with hexane:EtOAc 98:2 to afford 1-bromo-4-ethylthio-2-methoxybenzene as a colourless liquid in 17% yield, 1.00 g.
