Abstract

Procedure for preparation of quinazoline derivatives. The invention is related to a procedure for the preparation of quinazoline derivatives of general formula i, in which rbs1 and rbs2 can be equal or different and represent hydrogen or lower rent, or jointly form a group ethylene or trimethylene, yn is 2 or 3, characterized by the reaction of a 1,2 dimetoxy phenyl 4 istitiourea derivative, with a diamincarboxifuran derivative, eventually substituted, and posterior cyclation, thermal or catalytic, of the compound so obtained. The invention is also related, with the preparation of the intermediate reaction compounds. The compounds object of this invention have interesting properties pharmaceutical as antihypertensive and blockers of si1 receptors. (Machine-translation by Google Translate, not legally binding)
