Methods of preparing 3-phenyl (thio) uracils and 3-phenyl-dithio uracils

摘要

In, and prepared by reacting an enamine of the formula III Feniruiso of Formula II (thio) cyanate, or (thio) uracils 3-phenyl-dithio uracils of the formula I 3- phenyl, if appropriate, further In step, is reacted with an aminating agent of formula IV [wherein a ¹ = hydrogen R a R ¹ = R ^1a] of formula I obtained 3-phenyl or (thio) uracil 3-phenyl-dithio uracil wherein ¹ = R amino Formula I, L1 substituents R ^1, R ^1a, R ^2, R ^3, R ^4, X ^1, X ^2, X ^3, Ar, A and claim 1 respectively Te I describe a process for obtaining a] are as defined in the 3-phenyl or (thio) uracils 3-phenyl-dithio uracils.
