Abstract
IMPROVEMENTS INTRODUCED IN THE PURPOSE OF MAIN PATENT No. 324,465 for: "PROCEDURE FOR THE OBTAINING OF NEW PIRIDYL DIHYDROISOKINOLEINS of the general formula **(See formula)** in which the isoquinoline ring is attached at position 3 or 4 of the pyridine ring, and R1 represents an alkyl group containing from 1 to 5 carbon atoms or a benzyl group optionally substituted by a methyl group or a halogen atom, R2 represents an alkyl group with 1 to 5 carbon atoms or together with R1 and the adjacent carbon atom, a cycloalkane ring containing 5 or 6 carbon atoms, R3 represents a hydrogen or halogen atom or lower alkyl group and R4 and R5 which may be the same or different, represent hydrogen atoms or lower alkyl groups, as well as its addition salts with physiologically tolerable inorganic or organic acids, characterized by comprising the dehydrogenation of a tetrahydroisoquinoline of the general formula **(See formula)** where the symbols R1 to R5 have the meanings indicated above and the pyridine ring is linked in position 3 or 4 with the isoquinoline ring by means of a dehydrogenating agent or catalyst according to the classic procedures, and the eventual transformation of the compounds as well obtained in their addition salts with physiologically tolerable inorganic or organic acids.
