ARYLOXYAMINOBUTANOL DERIVATIVES AND A PROCESS FOR THE PREPARATION THEREOF

摘要

The invention relates to novel aryloxyaminobutanol derivatives of the general formula (I), (I) or their stereoisomers or non-toxic acid addition salts, wherein R stands for optionally halogeno or alkyl or alkoxy substituted phenyl or naphthyl group, and R1 stands for a C5-9 cycloalkyl-, C1-7 alkyl- or optionally halogeno or alkyl- or alkoxy substituted phenyl-alkyl group. These compounds possess valuable heart-specific pharmacological properties, and are practically free of harmful side-effects.
