Abstract
"Process for the preparation of di-guanilhydrazºnicos derivatives" of formula ** (See formula) ** wherein R means a lower alkyl moiety, characterized in that in a compound of formula ** (See formula) ** in which the X residues are transformable residues in radicals of formula ** (See formula) ** X is transformed into such radicals or compounds of formula ** (See formula) ** in which A means a transformable residue in the formula grouping ** (See formula) ** radical A/transforms into the formula grouping ** (See formula) ** or a compound of formula ** (See formula) ** preferably in the form of its mono-salt, it is reacted with a compound of formula ** (See formula) ** under the formation of a urea bridge, and, if desired, in the compounds obtained, within the range of the final compounds, the radicals are transformed to each other according to known methods and/or the free bases obtained are transformed into their salts or salts obtained in the free bases.
