Abstract
Process for the preparation of carbostyrilic derivatives and, more particularly, of 3,4-dihydrocarbostyril derivatives and intermediates, represented especially by the following formula, and their acid addition salts, pharmaceutically acceptable: **(See formula)** where R1 is chosen from the group comprising a hydrogen atom, a linear or branched alkyl group of 1 to 4 carbon atoms, an aralkyl group and an alkenyl group of 1 to 4 carbon atoms, and R'and R "can be equal or different from each other and each represents a hydrogen atom, a short-chain alkyl group of 1 to 4 carbon atoms, an aralkyl group or a cycloalkyl group, or R'and R ", taken together with the atom of nitrogen to which they are attached, can form a heterocyclic group that may contain an additional nitrogen atom or an oxygen atom as a ring member, characterized in that it consists in reacting a 3,4-dihydrocarbostryl derivative of the formula **(See formula)** where R1 is as described above and Z represents a group of the formula **(See formula)** where Y represents a halogen atom, with an amine of formula **(See formula)** where R'and R "are those previously described.
