Abstract

Procedure for obtaining compounds that have the general formula: **(See formula)** in which, R1 represents a hydrogen atom or an acyl group, R2 an alkyl or alkoxy group containing 1 to 5 carbon atoms, which can be straight or branched, or a cycloalkyl group with 5 or 6 carbon atoms, R3 represents a hydrogen atom or a lower alkyl group, and R4 a straight or branched alkyl group with 1 to 8 carbon atoms, a cycloalkyl group with a maximum of 7 carbon atoms, a benzodioxanyl-2-alkyl group, in which the alkyl group contains 1 to 4 carbon atoms or the group **(See formula)** in which Z represents a straight or branched group of alkylanes, containing from 2 to 6 carbon atoms, n the numbers 0 or 1, R5 and R6, which may be the same or different, hydrogen atoms, hydroxy groups, lower alkyl or lower alkoxy or together a methylene dioxy group, with the restriction that R4 does not represent an isopropyl group if it represents a hydrogen atom, and furthermore, that R2 represents a methyl or methoxy group, and R3 a atom of Hydrogen, a methyl or ethyl group, discretionally in the form of pure stereo isomers or pairs of diastereomeric antipodes and their acid addition salts characterized by: reduce an amide of a carbonic acid of general formula **(See formula)** in which R'preferably represents a hydrogenalitically separable group, remove from the compound the protection groups, if any, acylate the phenolic free OH groups, if desired, optionally, transform the free bases obtained first into their acid addition salts, the acid addition rooms obtained firstly in rooms with other acids or in free bases.
