Abstract
PROCESSO PARA A PREPARAçãO DE INTERMEDIáRIOS. A presente invenção refere-se a um processo para a produção de compostos intermediários de fórmula I no qual os substituintes são conforme definidos acima. O processo compreende reagir uma anilina substituida com HX aquoso, seguido pela remoção de água por destilação azeotrópica e diazotização e pirólise com um nitrito orgânico em temperaturas elevadas na auséncia de um catalisador de cobre. Alternativamente, HX gasoso pode ser usado para substituir HX aquoso no processo. Conseqúentemente, uma etapa de remoção de água por destilação azeotrópica pode ser eliminada, Os compostos intermediários de fórmula 1 são adequados como intermediários na preparação de derivados de 3-hidróxi-4-aril-5-oxopirazolina herbicidamente ativos.
