Versuchsvorschrift

37.6 g of (N-methylsulfonyl-N-methylamino)sulfonamide are dissolved in 500 ml of chlorobenzene, 51.8 g of phenyl 4-methoxy-6-methyl-2-pyrimidylcarbamate are added dropwise at room temperature to the solution, and the mixture is stirred for 5 hours at 100° C. The mixture is cooled to 0° C., the precipitate is then filtered off, and, after washing with 100 ml of chlorobenzene, 68.8 g of the desired product of a purity of 98.7% are obtained. This corresponds to a yield of 96.4% of theory. The melting point of the product is 118-120° C.
