PROCESS FOR OBTAINING O-(3-AMINO-2-HYDROXYPROPYL)-AMIDOXIMES

The compounds of general formula I, wherein R to R , m and n have the meaning given in Claim 1, are valuable medicaments which are suitable for the treatment of diabetic angiopathy. They are prepared by either reacting an amidoxime of formula II with epichlorohydrin to give an epoxide of formula IV and then reacting the epoxide with an amine of formula III or by directly reacting the amidoxime of formula II with a 3-amino-2-hydroxy-1-halogenopropane of formula Va, wherein X represents halogen, or a 3-amino-1,2-epoxypropane of formula Vb. Compounds of formula I, wherein R denotes hydrogen, are also prepared by reacting an amidoxime of formula II with a 2-phenyl-5-halogenomethyloxazolidine of formula VI, wherein X represents halogen, after which the ring compound obtained, of formula VII, is cleaved hydrolytically.
