Abstract

A procedure for the preparation of new derivatives of 1, 2, 3, 4-tetrahydroisoquinoline of general formula; **(See formula)** where R1 and R2 are each a hydrogen atom or a lower alkyl radical, X is an oxygen or sulfur atom and R3 is a phenyl radical with one to three substituents selected from the group consisting of a lower alkoxy, hydroxy, amino radical, nitro or lower haloalkyl and a halogen atom and pharmaceutically acceptable salts thereof, the process of which is characterized by removing the protecting groups of a compound of formula; **(See formula)** where R1 and R2 are as defined above, R8 and R9 are, individually or in combination with each other, hydroxy radical protecting groups and R7 is a phenyl radical with one to three substituents selected from the group consisting of a lower alkoxy, hydroxy radical which can be protected with a protecting group, amino, nitro or lower haloalkyl and a halogen atom, or a salt thereof.
