Abstract

Selon l'invention, on fait réagir le nitrofurfuraldéhyde-5 et l'acétone dans un milieu de support de réaction inerte sous agitation continue et à une température comprise entre 50 et 100 degrés C par l'action catalytique d'un halogénure métallique, après quoi on élimine l'eau provenant de la réaction pour obtenir un produit solide et cristallin séparable par filtrage, adéquat pour l'obtention, au cours de phase postérieures, de produits coccidiostatiques par des moyens conventionnels.
