METHOD FOR PESTICIDE PRODUCTION Russian patent published in 2006 - IPC C07D231/44 

FIELD: organic chemistry, agriculture.

SUBSTANCE: invention relates to method for production of compounds of general formula I wherein R¹ represents CN or CSNH₂; X represents N or C each R² and R⁴ are independently hydrogen or chlorine; R³ represents halogen, haloalkyl, haloalkoxy or SF₃; R⁵ and R⁶ are independently alkyl; n = 0, 1 or 2. Claimed method includes reaction of compound of formula II , wherein substituents are as defined above; W represent hydrogen, with metal inorganic salt or organic amine to form salt of compound II as intermediate and further reaction of said salt with alkylating agent of formula III wherein R⁶ is as defined above; Y represents leaving group. In another embodiment compounds of formula I are obtained by reaction of metal inorganic salt or organic base of formula II with abovementioned alkylating agent of formula III.

EFFECT: essentially decreased formation of side products; target products of high purity.
