(A) Alkanolamine derivatives (I) - where - R1 = alkyl (opt. substd. by one or more hydroxy groups), cycloalkyl or alkenyl or aralkyl group which may be opt. substd. by one or more halogen atoms and/or alkoxyl groups. - R2 = hydrogen or alkyl. - R3 = acyl. - R4 = acylamino, alkenyl, nitro, hydroxy, alkoxy, alkenyloxy, alkynyloxy, or aralkoxy. - In addition R2 and R3, together with the nitrogen atom, represent a cyclic imido group, in which case R4 can = hydrogen as well as the above values. - (B) Esters, aldehyde condensation products and acid addition salts of (I). - The compounds are sedatives, vasodilators, diuretics, hypotensives, myocardial depressives, and are agents for the treatment of Parkinson's disease. - 1-(4-acetamido-2-nitrophenoxy)-3-isopropylamino-2-propanol, m.p. 132-134 deg.C.
