USE: A herbicide for foliar treatment. It exterminates the broad-leaved weeds such as violet, Byzanitine speedwell, etc. almost completely, and suppresses the gramineous weeds such as SHIBA-MUGI to a certain extent. It has excellent selectivity, e.g. very low phytotoxicity to wheat.
PROCESS: The compound of formulaIcan be prepared, e.g. by reacting the aniline derivative of formula II with N-methoxy-N-methylcarbamyl chloride or N,N- dimethylcarbamyl chloride. The reaction is preferably carried out in a solvent such as benzene in the presence of a dehydrochlorinating agent such as pyridine.
