1,4-Disubstituted-5(4H)-tetrazolinones of the formula (I)
(wherein R¹, R² and R³ have the meanings given in the specification), which are known to be useful as herbicides, can be obtained in very good yields by reacting the corresponding 1-substituted-5(4H)-tetrazolinones with the corresponding carbamoyl chlorides in the presence of 4-dimethylaminopyridine.
The present disclosure provides compounds that include a tetrazolone derivative of a carboxyl group of an active agent. This disclosure also relates to pharmaceutical compositions that include these compounds, methods of using these compounds in the treatment of various diseases and disorders, and processes for preparing these compounds.
