Abstract
Procedure for the preparation of new amino-phenyl-ethanolamines of the general formula I ** (See formula) ** where R1 signifies a chlorine, bromine or iodine atom; R2 signifies a fluorine atom, a straight chain or branched alcohol group with 1 to 5 carbon atoms, a hydroxyalkyl, aminoalcohyl, dialkoylamino-alcohol, trifluoromethyl, alkoxy, nitro, cyano, carboxy, carbalkoxy or carbamoyl group; R3 and R4, which may be the same or different, mean hydrogen atoms, straight-chain or branched alcohol groups with 1 to 6 carbon atoms, hydroxyalkyl groups, cycloalkyl, cycloalkyl alkoxy or optionally substituted aralkyl groups, as well as their optically active antipodes and of its acid addition salts with physiologically compatible organic or inorganic acids, characterized in that a compound of the general formula II is subjected to halogenation, ** (See formula) ** wherein R2 through R4, are as initially defined; and a compound of the general formula I, obtained according to the procedure, in which R2 represents a cyano group, is then transformed, if desired, by means of hydrolysis, into the corresponding compound of the general formula I, in which R2 represents a carbamoyl or carboxyl group, and/or a compound obtained from the general formula I, in which R2 represents a carbamoyl or carbalkoxy group, is transformed if desired into the corresponding compound of the general formula I, where R2 means a carboxyl group, by hydrolysis, and/or a compound obtained from the general formula I is optionally split into its optically active antipodes and/or a compound of the general formula I, in which R3 or R4 represents an atom Hydrogen is transformed if desired by reaction with an aldehyde of the general formula IV R5 - CHO (IV) wherein R5 signifies a hydrogen atom or a straight or branched chain alcohol group, in an oxazolidine of the general formula Ia ** (See formula) ** wherein R1, R2 and R3 as well as R5 are as initially defined, and/or if desired is transformed into an acid addition salt with a physiologically compatible organic or inorganic acid.
