실험 절차

The substituted phenylthioacetonitrile starting materials can be prepared by the reaction of the corresponding thiophenol with chloroacetonitrile in alcoholic sodium hydroxide. In a representative procedure, a solution of 100 grams of 4-tert-butylthiophenyl and 45.3 grams chloroacetonitrile in 225 milliliters of 95 percent ethanol is stirred at room temperature while a solution of 24 grams sodium hydroxide in 36 milliliters water is added dropwise until the mixture remains alkaline to phenolphthalein. Slight spontaneous warming occurs during the addition. The mixture is then diluted with an equal volume of water and extracted twice with ether. The ether extract is washed with water, dried over sodium sulfate, and distilled, yielding the 2-(4-tert-butylphenylthio)acetonitrile as a liquid boiling at 153°-6°C. under a pressure of 4 millimeters of mercury.
