実験手順: Epibromohydrin (1.37 g.) in 2 ml. dry tetrahydrofuran is added to a stirred suspension of the salt obtained by mixing 3 g. of 4-methylbenzyl mercaptan and 550 mg. of sodium hydride (56% dispersion in mineral oil) in 60 ml. dry tetrahydrofuran. The resulting solution is heated at reflux for 4 hours. Thereafter, the solvent is removed and 30 ml. of water is added to the residue. The resultant aqueous mixture is extracted with ether and the ether extracts washed with water, dried over magnesium sulfate and evaporated to dryness to yield 1,3-bis(4'-methylbenzylthio)-2-propanol. obtained by mixing 3 g The resulting solution is heated at reflux for 4 hours Thereafter, the solvent is removed of water is added to the residue The resultant aqueous mixture is extracted with ether the ether extracts washed with water dried over magnesium sulfate evaporated to dryness
