Reaction Steps

12.4 grams (0.1 mole) of benzyl mercaptan were added to a solution of 2.3 grams of sodium in 75 ml of water free ethanol (corresponding to 0.1 mole of sodium ethanolate) and the mixture stirred for 0.5 hour at +10° C. Thereupon there were added 22.72 grams (0.09 mole) of 6-chloro-8-methylthiooctanoic acid ethyl ester (X) and the mixture heated for 20 hours at reflux. To the cooled reaction mixture there were added 11.2 grams (0.17 mole) of potassium hydroxide and stirring was carried out for 20 hours at room temperature. After addition of 500 ml of water the mixture was acidified with dilute hydrochloric acid, extracted with dichloromethane, the combined extracts washed with saturated aqueous sodium chloride solution and dried with sodium sulfate. By distilling off the solvent in a vacuum there were obtained 28.0 grams (96% of theory) of crude b 6-benzylthio-8-methylthiooctanoic acid.
