Abstract
N-(6-chloro-3-pyridyl)methyl-N-ethylamine is an important intermediate for the synthesis of nitenpyram. Its synthetic method is reformed. The optimal reaction conditions are as follows :n(2-chloro-5-chloro-methyl-pyridine)∶n(mono-ethylamine)=1∶1.8, reaction temperature 40~45℃ and time 3 h.The yield reaches 95%.
