ABSTRACT:
According to the process of the invention, the hexahydropyridazine-3-carboxylic acid derivatives are prepared by reacting a compound of formula (II)with a compound of formula (III)in the presence of a base with a pK of greater than or equal to 8.5, in a ketone organic solvent, to obtain an intermediate compound that is not isolated and that is treated with a basic aqueous medium.By means of this process, the derivatives are obtained more quickly and more economically.
