Procedure

An equivalent amount of sodium hydride (50% mineral oil dispersion) is added to a solution of N-[[4-(2-methoxyethylthio)-6-methylpyrimidin-2-yl]aminocarbonyl]-2,5-dichlorobenzenesulfonamide in dimethylformamide under a nitrogen atmosphere. After hydrogen evolution ceases, an equivalent amount of dimethylsulfate is added. After stirring for 12 hours the reaction mixture is poured into a large volume of water. The resulting precipitate is filtered to yield N-[[4-(2-methoxyethylthio)-6-methylpyrimidin-2-yl]aminocarbonyl]-2,5-dichloro-N-methylbenzenesulfonamide.
