FIELD: chemistry.
SUBSTANCE: invention relates to the method of obtaining the derivatives of 3-aroilantra(1,9-cd)isoxazol-6-one with the general formula of 
where X - hydrogen, halogen or the lowest alkyl, which are used as intermediate products in synthesis of derivatives 7,8-phthalylclaridone, used as dyes for the polyester fibres. The essence of the method lies in heating 1-hydroxytriazone-2-aroilantraquinone in acetic anhydride.
EFFECT: simpler technology and safer process.
