The desired product is isolated in a known manner in free form or as a salt. The process is usually carried out in an inert solvent, for example toluene or dioxane, in the presence of an acid-binding agent. For the preparation of pharmacologically acceptable salts, hydrochloric acid, hydrobromic, phosphoric, sulfuric acetic, citric, maleic or benzoic acid are used.
