ANALOGIFREMGANGSMAADE TIL FREMSTILLING AF TERAPEUTISK AKTIVE 4-AMINO-6,7-DIMETHOXYQUINAZOLINDERIVATER ELLER FARMACEUTISK ACCEPTABLE SYREADDITIONSSALTE HERAF

Alkylenediamine amides corresponding to the general formula (I) (I) in which R1 and R2 each represent, independently of one another, a hydrogen atom, an alkyl having 1 to 4 carbon atoms or the benzyl radical, n is equal to 2, 3 or 4 and R represents either a cycloalkyl radical having 3 to 6 carbon atoms, or a radical in which m is 0, 1 or 2, in which m is 0, 1 or 2 and p is 0, 1 or 2, and also their addition salts with pharmaceutically acceptable acids. These compounds may be prepared by reacting an aminoamide (III) with a 4-amino-2-halogeno-6,7-dimethoxyquinazoline (II). The compounds are useful in treating cardiovascular disorders, and pharmaceutical compositions containing the compounds are also claimed.
