A method has been developed for the synthesis of new 8-amino-substituted 5-propyl(isobutyl)-1,2,3,4-tetrahydropyrimido[4',5':4,5]furo[2,3-c]isoquinolines from 3-oxo derivatives of 5,6,7,8-tetrahydroisoquinolines. Isomeric triazoles, condensed at the edge [c] of the pyrimidine ring, have been obtained from the 8-hydrazino derivatives. A Dimroth rearrangement was carried out in acidic medium.
