Abstract

Procedure for the preparation of isoxazole derivatives of the formula: **(See formula)** wherein R1 and R2 each represent a member chosen from the group consisting of a hydrogen atom, a lower alkyl group, and a cycloalkyl group; R3 and R4 each represent a member chosen from the group consisting of a hydrogen atom, a lower alkyl group, a cycloalkyl group, a group is a member selected from the group consisting of a pyrrolidino group, a piperidino group, a piperazino group, and a morpholino group; Y is a divalent radical chosen from the group consisting of an oxo group, a thioxo group and an imino group, characterized in that it comprises reacting a reactive form of an isoxazol-3-carboxylic acid of the formula: **(See formula)** wherein R1 is defined as above and X is an anionic residue of carboxylic acid, with a substituted or unsubstituted urea derivative, of the formula: **(See formula)** wherein R2, R3, R4 and Y are defined as above.
