Procedure
0.88 g (0.005 mol) of 2-amino-4-methoxypteridine and 1.30 g (0.0052 mol) of 2-trifluoromethylphenylsulfonyl isocyanate were reacted in 40 ml of methylene chloride according to Example 4 to obtain 2.0 g (94% of theory) of N-4-methoxypteridin-2-yl)-N'-(2-trifluoromethylphenylsulfonyl)-urea in the form of light yellow crystals melting at 187° C.
