Procedure

To a dry stirred solution of 18.3 parts of 2-amino-4-(2-methoxyethoxy)-6-methylpyrimidine in 300 parts of methylene chloride at ambient temperature and pressure was added 22 parts of 2-chlorobenzenesulfonylisocyanate. The mixture was stirred for 2 hours and then the methylene chloride was removed under reduced pressure. The resulting solid was triturated with 1-chlorobutane and filtered to yield 35 parts of N-[[4-(2-methoxyethoxy)-6-methylpyrimidine-2-yl]aminocarbonyl]-2-chlorobenzenesulfonamide, m.p. 130°-140° C. The product showed characteristic absorption bands in the infrared spectrum.
