摘要:
This invention describes a method for preparing benzyluracils using methyl benzylcarbamates as intermediates. The method comprises the steps of contacting an alkali metal salt of an ester of 3-amino-4,4,4-trifluoro-2-butenoic acid with a methyl benzylcarbamate I to provide a benzyluracil II. ##STR1## where R, W, V, X and Y are as described in the specification.
