実験手順
The carboxylic ester compounds of the present invention may be prepared by reacting trichloroacetamidine with a selected acetoacetate to form the corresponding 4-hydroxy-2-trichloromethylpyrimidine, which is then reacted with a selected carboxylic acid chloride. These general reactions are illustrated below in equations (A) and (B). In equation (A), trichloroacetamidine is reacted with ethyl 2-chloroacetoacetate to form 5-chloro-4-hydroxy-6-methyl-2-trichloromethyl-pyrimidine. In equation (B), the 5-chloro-4-hydroxy-6-methyl-2-trichloromethylpyrimidine is reacted with trichloroacetyl chloride to form 5-chloro-6-methyl-4-trichloroacetoxy-2-trichloromethylpyrimidine. ##STR3##
