Procedure

A stirred mixture of benzylsulfamic acid (73 g), PCl5 (81 g) in toluene (540 ml) is heated to 40°-50° C. for one hour and refluxed for about 3 hours. The cooled mixture is filtered through Celite and the filtrate concentrated in vacuo to remove the toluene affording the desired product as a liquid.
