To a stirred suspension of K2CO3 (4.5 g, 32.6 mmol) and cyclohexylmercaptan (2.0 mL, 16.4 mmol) in DMSO (20 mL) was added 2-fluorobenzaldehyde (1.7 mL, 16.2 mmol) dropwise over 10 minutes at room temperature, and the reaction mixture was heated at 100° C. for 5 hours with stirring. After cooling to room temperature, the reaction mixture was partitioned between ethyl acetate and water. The organic layer was separated and the aqueous phase extracted with ethyl acetate (×3). The combined organic extracts were washed successively with sodium bicarbonate solution and brine, then dried over anhydrous magnesium sulfate, filtered and evaporated in vacuo to afford 2-(cyclohexylthio)benzaldehyde (3.22 g, 14.6 mmol, 90%) which was used directly without further purification.
