Abstract: 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.
