Изобретение относится к способам получения производных 3-фенилтиоантра [1,9-сd] -изоксазол-6-она, которые используются как исходное сырье для синтеза производных 5,6-фталилфенотиазина, применяемых в анилино-красочной промышленности для крашения полиэфирных волокон. Цель изобретения - упрощение технологии процесса и расширение ассортимента целевых продуктов. Для этого производные 1-гидрокситриазино-2-фенилтиоантрахинона нагревают в уксусном ангидриде или уксусной кислоте, содержащей до 10% уксусного ангидрида.The invention relates to methods for producing 3-phenylthioanthra [1,9-cd] -isoxazol-6-one derivatives, which are used as raw materials for the synthesis of 5,6-phthalylphenothiazine derivatives used in the aniline-dye industry for dyeing polyester fibers. The purpose of the invention is to simplify the process technology and expand the range of target products. To this end, 1-hydroxytriazino-2-phenylthioanthraquinone derivatives are heated in acetic anhydride or acetic acid containing up to 10% acetic anhydride.
