New piperidinyl-alkyl-benzamides and salts thereof are disclosed, together with a method for the production of the benzamides and salts. The benzamides, which have beta-adrenergic agonist effects, have the general formula ##STR1## The hydrochlorides which exemplify the salts, have the general formula ##STR2## In the foregoing formulas R is hydrogen, an alkyl group having from 1 to 4 carbon atoms, an alkoxy group having from 1 to 4 carbon atoms, halo, amino, hydroxy or trifluoromethyl, n is 1, 2 or 3 when R is methoxy but is otherwise 1, and x is 1, 2 or 3. The hydrochloride salts of the benzamides according to the invention can be produced by the reactions illustrated below: ##STR3## Wherein R, n and x have the meanings set forth above and Y can be --Cl, --F, or --OCH.sub.3.
