実験手順

The pyrimidinyl carbamate compounds of the present invention may be prepared by reacting trichloroacetamidine with the corresponding acetoacetate to form the corresponding 4-hydroxy-2-trichloromethylpyrimidine, which is then reacted with a selected carbamoyl chloride. These general reactions are illustrated below in equations (A) and (B). In equation (A), trichloroacetamidine is reacted with methylacetoacetate to form 4-hydroxy-6-methyl-2-trichloromethylpyrimidine. In equation (B), the 4-hydroxy-6-methyl-2-trichloromethylpyrimidine is reacted with dimethylcarbamoyl chloride to form 6-methyl-2-trichloromethyl-4-pyrimidinyl dimethylcarbamate. ##STR3##
