Reaction Steps

To a solution of 28.5 g of p-thiocresol in 250 mL of water is added 8.8 g of sodium hydroxide. The solution is heated on a steam bath briefly with vigorous stirring and then cooled to room temperature. To this solution is added 250 of toluene, 39.7 g of a 50% by weight solution of 3,4-methylenedioxybenzyl chloride in methylene chloride and 3.3 g of tetrabutylammonium chloride. This solution is stirred at room temperature for one hour and then 4.4 g of sodium hydroxide is added. The resulting solution is stirred at room temperature overnight and then partitioned. The organic layer is washed with 1N sodium hydroxide, brine, and dried over sodium sulfate. The solvent is removed at reduced pressure and the residual brown oil is purified via column chromatography using hexane/chloroform (2:1). This affords 24 g of the desired product as a clear oil. MS (CI): m/z 259 (MH+). Calcd for C15H14O2S: C=69.74, H=5.46, S=12.41 Found C=69.53, H=5.36, S=12.69
