Process for preparing new tiotropium salts of the formula 1 in which X ‾ means an anion, HO H 3 C + CH 3 OOSS characterized in that a tiotropium salt of the formula 2 HO NOH 3 C + CH 3 OOSS is reacted in where Y‾ means an anion other than X ‾, selected from the group of halides, with an AgX salt, in which X can have the meanings indicated above, in an appropriate solvent. |
