METHOD OF PRODUCING PESTICIDE COMPOUNDS Russian patent published in 2012 - IPC C07D231/44 

FIELD: chemistry.

SUBSTANCE: present invention relates to a method of producing a compound (I), where X is N or CR⁴; R¹ is CN or CSNH₂; R² and R⁴ are independently hydrogen or chlorine; and R³ is halogen, haloalkyl, haloalkoxy or SF₅, n equals 0, 1 or 2. The method involves, at the first step, reaction of a compound of formula (IV), where X, R¹, R², R³, R⁴ and n assume values given above, with formaldehyde or a formaldehyde trimer or chemical equivalent thereof, to obtain an intermediate compound (V), where X, R¹, R², R³, R⁴ and n assume values given above; and at the second step, reaction of the compound of formula (V) with a reducing agent, preferably sodium borohydride. The invention also relates to an intermediate compound 3-cyano-1-(2,6-dichloro-4-trifluoromethylphenyl)-5-hydroxymethylamino-4-trifluoromethyl thionyl pyrazole.

EFFECT: efficient method of obtaining the compounds.
