Method For Production Of 1-Alkyl-3-Phenyluracils
摘要：
The present invention relates to a process for preparing 1-alkyl-3-phenyluracils of the formula I where the variables R1 to R7 are as defined in the description by reacting 3-phenyluracils of the formula II and alkylating agents of the formula III R1-L1   III, with one another, wherein during the entire reaction the pH is kept in a range from 1 to 6 by adding base a little at a time.
摘要（中）：

本发明涉及一种制备式I的1-烷基-3-苯基尿嘧啶的方法，其中变量R1至R7如说明书中所定义，通过使式II的3-苯基尿嘧啶与式III的烷基化剂反应， in-line-formula description =“In-line Formulas”end =“lead”？> R1-L1 III，<？in-line-formula description =“In-line Formulas”end =“tail”？> ，其中在整个反应期间，通过一次添加碱几乎将pH保持在1至6的范围内。
