ABSTRACT OF THE DISCLOSURE The present invention provides processes for the pro- duction of new basically substituted alkoxypyridinecarboxamides of the general formula I Image (I) wherein R1 represents alkyl containing 1 to 4 carbon atoms and -OR1 is in adjacent position to the carboxamide group, R2 represents alkyl containing 1 to 4 carbon atoms or an ethylene radical which is attached to one of the tri- valent radicals designated as A and the nitrogen atom located between it to form a 6-membered ring, A represents trimethylene or tetramethylene, if R2 is alkyl as defined above, or, if R2 is an ethylene rad- ical, represents the 1-propanyl-3-ylidene radical linked in its 1-position with the nitrogen atom, if m is 1, or the 1,2,4-butane-triyl radical linked in its 4-position with the nitrogen atom and in its 2-position with R2, if m is 0, and one of the factors m and n is 0 and the other is 1, and the ring B is substituted only by OR1 or additionally by halogen with an atomic number up to 35, alkyl containing 1 to 4 carbon atoms and/or alkoxy containing 1 to 4 carbon atoms, and of acid addition salts thereof. These new substances possess valuable pharmaco- logical properties, in particular antiemetic, psychosomatic and antipsyehotic activity and can be used for the treatment of thought disturbances and of states of psychomotor excitation.
