Reaction Steps
To a solution of 2.50 g of 3,4-dimethoxy-α-[(4-methylphenyl)thio]benzeneacetonitrile in 50 mL of tetrahydrofuran, under an argon atmosphere with stirring, is added 0,367 g of 60% sodium hydride in oil. After 1.5 hours, 10.0 g of 1,11-dibromoundecane is added and stirring is continued for 43 hours. The reaction mixture is evaporated and the residue partitioned between diethyl ether and water. The organic phase is separated, washed with water, dried with magnesium sulfate, filtered and evaporated leaving an oil. The oil is purified via column chromatography, using hexane/ether (1:1) to afford 3.25 g of the desired product as a colorless oil.
