FIELD: chemistry.
SUBSTANCE: invention relates to variants of the method for obtaining the compounds of formula (I)
, which has several potentially useful biological reactions, including antibacterial, antioxidant, and anticancer activity, or a salt or solvate thereof, to processes for preparing intermediates, as well as to intermediates for preparing a compound of formula I. One embodiment of a process for preparing a compound of formula I involves aromatization compounds of formula (II)
, where X represents Cl, Br or I.
EFFECT: technical result is the development of a highly productive synthesis of the compound of formula I without any potential problems with toxicity.
