Abstract

Process for the preparation of a derivative of a substituted pyrazolidine and, more particularly, for the preparation of the equimolar salt of piperazine and of diphenyl-1,2-butyl-4-dioxo-3,5-pyrazolidine, characterized by by dissolving anhydrous piperazine and diphenyl-1,2-butyl-4-dioxo-3,5-pyrazolidine separately in the same organic solvent chosen from ketones, ethers, esters and aliphatic chlorinated hydrocarbons according to the formula Cx Hy Clz, in which x = 1,2 or 3; y = 0 to 6 included and z = 1 to 6 included, the solutions obtained being mixed together with stirring and a temperature between 20ºC and the boiling temperature of the solvent, adding seed crystals to the reactive mixture that is subjected to stirring until it is obtain a precipitate of the salt to be obtained, said precipitate then being separated by filtration, washing and drying.
