Abstract
"PROCESSO PARA A PREPARAçãO DE UM COMPOSTO, E, COMPOSTO". A invenção refere-se a um método para a preparação de 1-alquil-3-aril-5-difluorometóxi-1H-pirazóis da fórmula (I): em que arila representa um anel fenila mono- ou polissubstituído, R^ 1^ representa alquila C~ 1-C~ 4~, no qual, em um primeiro estágio de reação, um <225>-cetoéster da fórmula geral (II): é reagido com hidrazina e o produto de reação obtido é sucessivamente reagido como clorodifluorometano e um composto R^ 1^-L, em que R^ 1^ possui os significados antes mencionados e L representa um grupo de saída de uma reação de deslocamento nucleofílico.
