Versuchsvorschrift
With stirring at ambient temperature, 1.0 g of 2-aminopyrimidine in 25 ml of anhydrous acetonitrile was added to 2.4 g of 2-methoxycarbonylbenzenesulfonylisocyanate. After stirring that mixture for 24 hours, the resultant precipitate was filtered off to yield 2.2 g of the desired compound which melted at 188°-192°. Its showing infrared absorption peaks at 1700, 1680 and 1580 cm-1 is consistent for N-[(pyrimidin-2-yl)aminocarbonyl]-2-methoxycarbonylbenzenesulfonamide.
