Abstract

NEW MATERIAL:A urea derivative of formula I (A is methyl or methoxyl).
EXAMPLE: N'-[2-(Pentafluorophenoxy)pyridyl-5]-N,N-dimethylurea.
USE: A herbicide capable of exhibiting a strong herbicidal activity against broad-leaf weeds, e.g. green amaranth, and gramineous weeds, by the pre-emergence soil treatment with high safety for crops, e.g. soybeans, and no phytotoxicity in the usual amount of the drug.
PROCESS: 2-Pentafluorophenoxy-5-aminopyridine of formula II is reacted with N,N- dimethylcarbamyl chloride or K-methoxy-N-methylcarbamyl chloride in an inert solvent, e.g. benzene, at 0W150°C for 30minW10hr to give the compound of formula I. A base, e.g. pyridine, is used as a dehydrohalogenating agent.
