実験手順
To a solution of (3,5-dichlorophenylthio)acetonitrile (1.2 g) in 3.0 mL of ethylene glycol dimethyl ether is added 0.61 mL of 10M borane dimethyl sulfide complex and the mixture heated at reflux for 0.5 hours. The reaction is cooled in an ice bath and 2.0 mL of water and 2.0 mL of concentrated hydrochloric acid is added. This mixture is heated at reflux for 0.5 hr. The clear solution is then cooled and basified with 5N sodium hydroxide and extracted with ether. The ether extract is dried over potassium carbonate, filtered and concentrated to give 1.0 g of a colorless oil.
