Procedure

A suspension of potassium tert-butoxide (1.12 g, 10.0 mmol) and phenyl-methanethiol (1.24 g, 10 mmol) in THF (30 mL) at room temperature was stirred for 10 minutes before treating with 2-fluoro-6-iodo-benzonitrile (2.47 g, 10 mmol). The solution was stirred for 1 hour at room temperature, poured into a saturated ammonium chloride solution and filtered. The filter cake was recrystallized from hexanes to provide 2.41 g (53% yield) of the desired product. MS (ESI(−)) m/e 350.0 (M−H)−.
