Procedure

18.2 g of 2-(2,6-dimethyl phenylthio) 1-hydroxy ethane and 50 ml chloroform are added in a flask and when the mixture is perfectly clear, it is cooled to 0°. To the solution 14.3 g of phosphorous tribromide are added while keeping the temperature to about 0°. After completion of the addition, the inner temperature is let to revert at ambiant temperature then heated to reflux for one hour.
