Abstract
A process for the preparation of 1,2-diphenyl-3,5-dioxo-4-N-butyl-pyrazolidin derivatives of the formula: ** (see formula) ** Where n = 1 or 2 and r is represented by organic compounds of basic character: (see formula) tetrahydro-1,4-oxacin (see formula) hexahydropyridine (see formula) hexahydropyrazine And characterized essentially that when the reaction is verified with tetrahydro oxacin, the formed compound has the following structure: (see formula) (Machine-translation by Google Translate, not legally binding)
