Abstract: A method for the treatment of cognitive and behavioral disorders associated with aging and with dementia syndromes, for example senile dementia, Alzheimer's type, by administering a 2-amino-4-morpholino-6-propyl-1,3,5-triazine of the formula ##STR1## in which R.sub.1 =hydrogen, alkyl, aralkyl or acetyl, R.sub.2 =hydrogen, hydroxyl, alkyl, hydroxyalkyl, alkoxyalkyl, dialkylamino, aryl-hydroxyalkyl, (hydroxycycloalkyl)alkyl, alkanoyloxyalkyl, benzoyloxyalkyl, phenylacetyloxyalkyl, aminocarbonyloxyalkyl, COR.sub.3, where R.sub.3 =alkyl, aryl, halogenoaryl, alkylaryl, alkoxyaryl, aralkyl or aryloxy, CONR.sub.4 R.sub.5, where R.sub.4 and R.sub.5 =hydrogen or alkyl, or R.sub.1 and R.sub.2 form an alkyleneimino substituted by hydroxyalkyl, and in addition when R.sub.1 =acetyl, R.sub.2 =acetoxyalkyl, or a salt thereof.

Abstract: 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, orR.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 ofR.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.
