Abstract
Method for obtaining new derivatives of isoteophyllins, in particular 9- (beta-aminoethyl) -isoteophyllins, of the general formula: **(See formula)** wherein 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 from 1,3-dimethyl -4,5-diaminouracils, suitably substituted, is operated by condensation of the substituted 1,3-dimethyl-4,5-diaminouracils, of the general formula: **(See formula)** wherein R1 and R2 have the aforementioned meaning with carbon sulfide and cyclization to 8-mercapto-9- (beta-aminoethyl) -isotheophyllines and then desulfurizing the compound mercapto, preferably with Raney nickel.
