Procedure

A suspension of 3.3 g of the (N-(n-butylamino carbonyl) derivative of (XXV) in 75 ml of xylene containing 0.5 g of DABCO was heated to 125°-130° and a solution of 1.8 ml of liquid phosgene in 2 ml of xylene was added. The mixture was heated at reflux for an additional 1.5 hour, cooled under nitrogen, and concentrated to dryness in vacuo. A sample of the crude product displayed a characteristic sulfonyl isocyanate band in the IR at 2200 cm-1.
