METHOD FOR PREPARING OF STEREOISOMERS

摘要

The compounds can be used in preparing of drugs for treatment of cardiac arrythmia. According to the method there are synthesized the stereoisomers 4-/3-/-((R+)-propylsulphinyl)propyl/amino/-2(R)-hydroxypropoxy/ben zonitrile,4-/3-/ethyl/3-((S+)-propylsulphinyl)propyl/amino/-2(R)-x ydroxypropoxy/-benzonitrile,4-/3-ethyl/3-((R+)-propylsulphinyl)pro pyl/amino/-2(S)-hydroxypropoxy/benzonitrile,4/3-ethyl/3-((S+)-prop ylsulphinyl)propyl/amino/-2(S)-hydroxypropoxy/-benzonitrile and their pharmaceutically acceptable salts.
