New substituted 1-(1H-imidazol-4-yl)alkyl-benzamides and their salts, processes for the preparation thereof and pharmaceutical compositions. These compounds have the formula ##STR1## wherein R.sub.1, R.sub.2 =hydrogen or C.sub.1 -C.sub.4 -alkyl, R.sub.3 =hydrogen, amino, hydroxyl, C.sub.1 -C.sub.4 -alkyl or C.sub.1 -C.sub.4 -hydroxyalkyl, R.sub.4 =hydrogen or C.sub.1 -C.sub.4 -alkyl, or R.sub.3 R.sub.4 N=pyrrolidino, piperidino or morpholino, R.sub.5 and R.sub.6 =hydrogen, hydroxyl, C.sub.1 -C.sub.4 -alkyl or C.sub.1 -C.sub.4 -alkoxy, at least one of R.sub.5 and R.sub.6 being other than hydrogen. These compounds are prepared either by reacting a nitrogen compound with an alkyl 1-(1H-imidazol-4-yl)alkyl-benzoate or with a 1-(1H-imidazol-4-yl)alkyl-benzoic acid, or by hydrolyzing in an acid medium a 2-hydroxy-3-[1-(1H-imidazol-4-yl)alkyl]-benzonitrile. The compounds have anti-ischemic and .alpha..sub.2 -adrenoceptor agonist activities.
