Versuchsvorschrift

To 1.23 g of 2-amino-4,6-dimethyl-1,3,5-triazine in 30 ml of anhydrous methylene chloride was added with stirring 2.7 g of 2-methoxycarbonyl-3-thiophenesulfonylisocyanate. The mixture was heated to the boiling point and allowed to cool and stir at ambient temperature for sixteen hours. The solid thus obtained was removed by filtration to yield 2.3 g of the crude desired product melting at 158°-178°. The product showed peaks at 1720 and 1710 cm-1, by infrared absorption spectroscopy, consistent for the desired product.
