실험 절차

A suspension of 6 g of N-(butylaminocarbonyl)-2-(isoxazol-5-yl)benzenesulfonamide, prepared in Example 6, in 50 ml of xylene containing 0.2 g of DABCO was heated at 130°-135° C. while 1.6 ml of phosgene was added portionwise at a rate to maintain a reflux temperature of 130°-135° C. The mixture was refluxed for an additional 2 hours, cooled under nitrogen to room temperature, filtered, and the filtrate was concentrated to dryness in vacuo. A sample of the crude oily product displayed a characteristic sulfonyl isocyanate band in the IR at 2200 cm-1.
