Abstract

Настоящее изобретение предусматривает способ получения промежуточных соединений для получения азоксистробина, включающий проведение реакции соединения A и дихлорпиримидина в присутствии триметиламинового катализатора с добавлением раствора метоксида натрия в метаноле или добавлением метоксида натрия и метанола по отдельности с получением смеси соединения B и соединения C. В настоящем изобретении соединение B и соединение C, представляющие собой промежуточные соединения для получения азоксистробина, синтезируют из соединения A, при этом катализ осуществляют посредством применения триметиламинового катализатора, обеспечивающего протекание реакции с высокой эффективностью и высоким выходом. Кроме того, триметиламиновый катализатор характеризуется низкой точкой кипения и, таким образом, его можно легко регенерировать, благодаря чему содержание аммиачного азота в сточных водах может быть снижено и могут быть также снижены сложности и высокая стоимость обработки сточных вод. Регенерированный триметиламиновый катализатор может быть использован повторно в получении промежуточного соединения B, при этом он также характеризуется высокой каталитической активностью и также может обеспечивать высокий выход продуктов. Способ согласно настоящему изобретению имеет значительные преимущества по затратам при синтезе и является подходящим для производства в промышленном масштабе.
