3-Chloro-5-(trifluoromethyl)-2-pyridinamine → HCID 13064156, compound

Participants

Reaction Steps

For example, 2-amino-3-chloro-5-trifluoromethylpyridine is reacted with 2,6-difluorobenzoylisocyanate in toluene at 40° C. for 30 minutes, whereby N-(2,6-difluorobenzoyl)-N'-(3-chloro-5-trifluoromethyl-2-pyridyl)urea having a melting point of 214° to 217° C. can be obtained. This compound is effective in inhibiting and controlling various pests, particularly noxious insects. For example, in the insecticidal testing of the compound in a concentration of 800 ppm against larvae of diamondback moth in 3rd or 4th instar, a 100% insecticidal effect can be obtained.
