3.3 g (4.9 mmol) of 1,1′-thiodi-[5-(2,6-dichloro-4-trifluoromethylphenyl)-2-methylbenzene], 3.0 g (19.5 mmol) of Rongalite and 3.0 g (17.6 mmol) of isopropyl iodide were stirred in 30 ml of N,N-dimethylformamide at room temperature for 3 hours. The resulting reaction mixture was poured into 300 ml of water and extracted with 50 ml of ethyl acetate twice. The ethyl acetate layer was washed with 50 ml of water twice and dtied over anhydrous magnesium sulfate, and the ethyl acetate was distilled off under reduced pressure. Purification of the residue by silica gel column chromatography afforded 1.4 g of [5-(2,6-dichloro-4-trifluoromethylphenyl)-2-methylphenyl] isopropyl sulfide (yield 38.0%) as a yellow dough (nD20 1.5462).
