Versuchsvorschrift

5 g of lithium aluminum hydride are suspended in 200 ml of tetrahydrofuran, and a solution of 31.9 g of methyl 4-(3-chloropropylthio)benzoate in 200 ml of tetrahydrofuran is added thereto at 5° to 15° C. The mixture is stirred at the same temperature for 45 minutes. Water is added to the mixture at a temperature of below 20° C., and insoluble materials are filtered off. The filtrate is concentrated under reduced pressure to remove solvent, and the residue is distilled under reduced pressure. 24.1 g of 4-(3-chloropropylthio)benzylalcohol are obtained as an oil. Yield: 85%.
