Vorschrift

A solution of 4.2 g of 2-amino-4-chlorodifluoromethyl-6-methoxy-1,3,5-triazine (20 mmol) in 20 ml of methylene chloride was treated at 25° C. with a solution of 4.6 g of 2-nitrobenzenesulfonyl isocyanate (20 mmol) in 5 ml of methylene chloride. The mixture was subsequently stirred at 25° C. for 16 h, and the deposited product was filtered off with suction, washed with a little ether and dried at 40° C. in a water-jet vacuum. 3.1 g of the title compound (35% of theory) of m.p. 181° C. were thus obtained.
