Procedure

A mixture of 9.25 gm. (0.05 m) 5-mercaptopyridoxine, 4.75 gm. (0.025 m) of ethane-1,2-disulfonic acid, and 40 ml. of water is heated briefly until solution occurs. The solution is cooled and the precipitate collected by filtration. Recrystallization from methanol gives bis(2-methyl-3-hydroxy-4-hydroxymethyl-5-mercaptomethylpyridinium) ethane-1,2-disulfonate.
