FIELD: chemistry.
SUBSTANCE: claimed invention relates to method for obtaining chiral compound of formula 
or its salt, where Y1 and Y2 independently stand for F or Cl, preferably F, as well as to crystalline chiral compound of formula (IX) or its salt, in which from 80 to 95%, preferably from 85 to 95% of molecules of said crystalline compound or its salt are contained in form of cis-isomer of formula 
or its salt and from 20 to 5%, preferably from 15 to 5% of molecules of said crystalline compound or its salt are contained in form of trans-isomer of formula 
or its salt, and to its application for obtaining fungicidal preparation.
EFFECT: increase of method efficiency.
