Abstract
Abstract4-Amino-5-benzoyl(acetyl)isoxazole-3-carboxamides were prepared by cyclization of α-hydroxyimino nitriles O-alkylated with bromoacetophenones (bromoacetone). The purity of the target 4-aminoisoxazoles can be substantially increased by treating O-alkylated oximes with LiClO4 before cyclization.
