Abstract
Preparation procedure for benzamides of general formula **(See formula)** as well as its addition salts with pharmaceutically acceptable organic or mineral acids, and its quaternary ammonium salts, formula I in which A can be either a low molecular weight mono- or dialcoylamino radical, in which the alcohol groups can be linked together to form a cycle with or without nitrogen, oxygen or sulfur, the nitrogen atom being able, when the cycle contains it, to be linked to a low molecular weight alcohol group, the cycles being thus formed, for example, pyrrolidinyl, piperidinyl, imidazolidinyl, piperazine, morpholino and thiazolidinyl, or else a heterocyclic radical of the form **(See formula)** where R is a low molecular weight alcohol or alcohol radical, and m is an integer of less than 4; B can be a low molecular weight alcohol radical or an alcohol radical; n = 1 or 2, and X can be an amino, mono- or dialkoxylamino, alcoholic or alcoholic radical, a process that comprises treating a disubstituted benzoic acid in positions 2 and 5, of the formula **(See formula)** where B and X have the same meanings as above, with carbonyldiimidazole, of the formula **(See formula)** and reacting the compound obtained, of the formula **(See formula)** with an amine of formula H2N (CH2) n A (V), where A has the same meaning as above, to obtain the desired benzamide of formula (I).
