실험 절차

To a stirring solution of NaOH (11.26 g, 281.6 mmol) in water (500 mL) was added dropwise a solution of 4-fluorothiophenol (25 mL, 234.6 mmol) in methanol (50 mL). After 15 minutes ethyl bromide (14.4 mL, 281.6 mmol) was added. After 6 hours more NaOH (1 g) was added and the reaction mixture was extracted with ether (3×300 mL). The combined organic extracts were treated with brine followed by MgSO4 then concentrated down to give 1-(ethylthio)-4-fluorobenzene (29 g, 80%) as a slightly yellow colored liquid.
