The synthesis method comprises the following steps: (1) carrying out an HECK reaction on tert-butyl-N-methyl-4-vinylphenyl carbamateand 2-bromo-5-iodopyridine to obtain an intermediate A; and (2) condensing the intermediate A and triethylene glycol to obtain a target compound, namely the AV-45 intermediate. According to the invention, a conventional synthesis method of (E)-tert-butyl-4-(2-(6-(2-(2-(2-hydroxyethyl)ethoxy)ethoxy)pyridin-3-yl)vinyl)phenyl(methyl)carbamate is improved; few reaction steps are included, and the useof reagents with pungent smell is avoided; and of the intermediate and the target compound prepared through the method can be direct purified through recrystallization, operation is simple, and yieldis high.

The present invention includes insecticidal carbamates that are useful, for example, for the control of insects, such as mosquitoes, which can be used in applications where exposure to and / or contact with humans is likely. The insecticides of the present invention include phenyl N-methyl carbamates and compositions comprising them that exhibit species-selective inhibition of acetylcholinesterase (AChE) and are preferably toxic to mosquitoes but not humans. Of particular interest are compounds of Formula (I) and Formula (II):Compounds of Formula (I) and Formula (II) are especially suitable for insecticide treated nets and indoor residual spraying for mosquito control.
