Abstract

Procedure for the production of ortho-substituted phenylethylanines corresponding to formula I-a **(See formula)** where R1 represents hydrogen, hydroxyl, chlorine or lower alkoxy or lower alkyl which comprise at most 4 carbon atoms, R'2 represents hydroxyl or methoxy and B represents alkyl, isoalkyl or cycloalkyl, each with 3 to 8 carbon atoms, inclusive, or the group -CR3R4R5, in which each of the symbols R3, R4 and R5 represent methyl or ethyl, and its acid addition salts, characterized by the reduction of a compound of formula II **(See formula)** where A represents the carbonyl group or the methylene group, B'has the meaning previously attributed to B, and may also represent alkanoyl or isoalkanoyl comprising 3 to 8 carbon atoms, inclusive, provided that only one of the symbols A and B'comprise a carbonyl group, and R1 and R2 have the same meaning as before, in an inert solvent, by means of a complex metal hydride or by means of borane or diborane; conversion, if desired, of a product in which R1 is lower alkoxy and/or R'2 is methoxy into the respective compound in which R1 and/or R'2 are hydroxyl, by cleavage of ether; and conversion of a product into an addition salt with an inorganic or organic acid.
