Abstract:
This invention describes a new and convenient single step process for preparing 2-aryl-3-substituted-4(3H)-pyrimidinone herbicides by reacting a N-substituted amidine (or its hydrohalide salt) with a .beta.-keto ester under conditions of high pressure. The 2-aryl-3-substituted pyrimidinone compounds produced by the process of the present invention are very useful as herbicidal agents for the control of weeds in agronomically important crops.
