Abstract: Method for optically resolving an enantiomeric mixture of ethodolic acid to produce the S (+) enantiomer is provided wherein the enantiomeric mixture is salified with at least 0.5 moles per mole of a mixture of alpha-(+)-phenethylamine enantiomers in an organic solvent. The resulting precipitate containing the salt of optically active phenethylamine and the S-(+)-enantiomer of the ethodolic acid is separated followed by isolation of the optically enantiomer. Salification of the acid with organic and inorganic bases, selected from basis amino acids, morpholine, aminopyridine and benzylalkyltrimethylammonium derivatives provides new therapeutically effective derivatives.
Abstract: The invention provides novel phenyl-alkyl-imidazoles of the formula ##STR1## wherein A, R.sup.1, R.sup.2, m and n are as defined in the specification, and the group --(CH.sub.2)n--A--R.sup.1 is at the 3- or 4-position, together with their pharmaceutically acceptable salts. These phenyl-alkyl-imidazoles and salts have valuable pharmacological properties, especially CNS activities and activity against inflammatory disease.
