Reaction Steps
30.7 g (0.25 mole) of 2-amino-4,6-dimethylpyrimidine were dissolved in 350 ml of dichloromethane and a solution of 52 g (0.26 mole) of 7-oxabicyclo[2.2.1]hept-2-en-6-ylsulfonyl isocyanate (Diels-Alder adduct of vinylsulfonyl isocyanate and furan) in 100 ml of dichloromethane was added at 0° C. with stirring. The mixture was stirred a further 12 hours at room temperature, cooled to 0° C. and n-hexane was added. The precipitated reaction product was filtered off with suction, washed with n-hexane and dried. 73.6 g (90.8% of theory) of N-[(4,6-dimethylpyrimidin-2-yl)aminocarbonyl]-7-oxabicyclo[2.2.1]hept-2-en-6-ylsulfonamide having a melting point of 125°-145° C. were obtained.
