Reaction Steps

3-(Bromomethyl)tetrahydro-2H-thiopyrane 1,1-dioxide (1 g) is dissolved in 40 mL of N,N-dimethylformamide. 4-Bromo-3,5-dimethylphenol (885 mg) and cesium carbonate (2.85 g) are added and the reaction mixture is stirred at 130° C. overnight. The reaction mixture is concentrated under vacuum. Water is added and the mixture is extracted with ethyl acetate, The organic phase is separated, dried over sodium sulfate and concentrated under vacuum. The residue is chromatographed on silica gel (cyclohexane/ethyl acetate 100:0→80:20) to give the title compound. Yield: 800 mg.
