Abstract

Patente de Invenção: <B>"PROCESSO PARA PREPARAçãO DE 2-CLORO-5-AMINOMETILTIAZOL PARTINDO DE 2-CLORO-5-METILTIAZOL E PASSANDO POR-2-CLORO-5-CLOROMETILTIAZOL"<D>. A presente invenção refere-se a um processo para preparação de 2-cloro-5-aminometiltiazol, que é caracterizada pelo fato de halogenar-se em uma primeira etapa 2-cloro-5-metiltiazol com um agente de cloração radical na presença de um formador de radical e na presença de um diluente estável contra agente de halogenação radical até uma conversão de 40 até 70% em peso e, em seguida, em uma segunda etapa reagir-se a mistura de reação originada com amoníaco ou solução de amoníaco aquoso e isolar-se o 2-cloro-5-aminometiltiazol de maneira usual.
