Abstract

Production method of 9- (beta-aminoethyl) -isoteophilins, of the general formula: **(See formula)** where R1 and R2 are hydrogen atoms, alkyl, hydroxyalkyl radicals or, together with the nitrogen atom, a substituted or unsubstituted heterocyclic moiety that may in turn contain another heteroatom, characterized in that you will start from 1,3-dimethyl-4 5-diaminouracils, suitably substituted, are operated by condensation of 1,3-dimethyl-4,5-diaminouracil of the general formula: **(See formula)** wherein R1 and R2 have the aforementioned meaning with formic acid orthoesters under ring closure.
