Abstract
В заявке описан способ получения промежуточных соединений формулы И, в которой заместители являются такими, как определено в изобретении. Способ заключается в том, что замещенный анилин взаимодействует с водным раствором НХ с последующим удалением воды при помощи азеотропного отгона, и проводят диазотирование и пиролиз с использованием органического нитрита при повышенных температурах при отсутствии медьсодержащего катализатора. Альтернативно, в способе вместо водного раствора НХ можно использовать газообразный НХ. Поэтому в таком случае можно исключить стадию удаления воды с помощью азеотропного отгона. Промежуточные соединения формулы И применимы как промежуточные продукты для получения гербицидно активных замещенных 3-гидрокси-4-арил-5-оксопиразолинов.(I)
