Procedure
0.96 g of sodium tert-butylate was added to a suspension of 1.05 g of 2-amino-4-methoxy-6-methyl-1,3,5-triazine in 20 ml of dimethylacetamide (DMA) at room temperature, with vigorous stirring, to form a first mixture. A solution of 1.12 g of diphenyl carbonate in 10 ml of DMA was then added to the first mixture, in the course of 7 minutes, while it was cooled in an ice bath, to form a second mixture. The second mixture was subsequently stirred for another 15 minutes while cooled in the ice bath, and a solution of 1.84 g of methyl 2-aminosulfonyl-4-iodobenzoate (92.5% pure) in DMA was then added dropwise in the course of 7 minutes. When the reaction ended, the product was worked up as described in Example 1. 1.47 g of the desired product (58% of theory) was thus obtained.
