FIELD: chemistry.
SUBSTANCE: invention relates to the method of obtaining the derivatives 3-aroilanra-(1,9-cd)isoxazole-6-one of the general formula 
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 various polymeric materials and polyester fibres. The essence of the method lies in boiling 1(triazene-N-sulfonate)-2-aroihtranquonine in spirit solution of alkali with the subsequent neutralisation by acetic acid.
EFFECT: simpler technology and safer process.
