Reaktionsschritte

The crude 2-ethenyl-N-[(4,6-dichloro-1,3,5-triazin-2-yl)aminocarbonyl]benzenesulfonamide of Example 6 is contacted with methanol (10 ml) and then with a solution of sodium methoxide (14 mmol) in methanol. The mixture is then stirred at room temperature for 1.5 hours and evaporated to dryness. Subsequently, the residue is taken up in water, filtered to remove unwanted solids, and acidified to precipitate the product. The crystalline product obtained can be purified by chromatography on silica gel or recrystallization to yield the title compound.
