Abstract
Patente de Invenção: "PROCESSO PARA CRISTALIZAçãO DE N-(4-TRI-FLUORMETILFENIL)-5-METIL-ISOXAZOL-4-CARBOXAMIDA". A invenção refere-se a um processo para obtenção de N-(4trifluormetilfenil)-5-metil-isoxazol-4-carboxamida na forma cristalina, que é essencialmente livre de subprodutos. Além disso N-(4-trifluormetilfenil)-5metil-isoxazola-4-carboxamida é levada a um solvente orgânico ou a misturas de solventes orgânicos e água, a quantidade de subprodutos na solução é determinada por análise quantitativa, e uma quantidade eq³imolar de uma base é adicionada. A partir da solução obtida separa-se por cristalização N-(4-trifluormetilfenil)-5-metil-isoxazol-4-carboxamida.
