Abstract

A procedure for the preparation of 1,2,3,4-tetrahydroisoquinoline derivatives of the general formula: **(See formula)** where R1 and R2 are each hydrogen or lower alkyl, R3 is phenyl having substituent (s) selected from the group consisting of lower alkenyloxy, mercapto, lower alkylthio, sulfamoyl, and disubstituted mono or sulfamoyl, or a heterocyclic group, R'4 and R'5 are each hydroxy or a protected hydroxy and X is -0- or -S- and a pharmaceutically acceptable salt thereof comprising reacting a compound of the general formula: **(See formula)** where R1 and R2 are each as defined above, R4 and R5 are each hydroxy or a protected hydroxy, or a salt thereof, with an aldehyde compound of the general formula: R3-X-CH2CHO where R3 and X are each as defined above, or a reactive derivative thereof, and optionally subjecting the resulting compound to a removal reaction of the hydroxy protecting group.
