1,3-dimethyl-2-[(3-chloro-2-oxopropyl)thio]-1H-imidazolium chloride → 1,3-dimethyl-2-({3-[(1-methyl-1H-tetrazol-5-yl)thio]-2-oxopropyl}thio)-1H-imidazolium chloride

Participants

Reaction Steps

To a solution of 0.271 g (0.00196 mol) of 5-mercapto-1-methyltetrazole sodium salt hydrate in 30 mL of absolute ethanol was added 0.50 g (0.0020 mol) of 1,3-dimethyl-2-[(3-chloro-2-oxopropyl)thio]- 1H-imidazolium chloride whereupon a white precipitate formed immediately. The precipitate was removed by filtration and was recrystallized from ethanol to obtain the desired 1,3-dimethyl-2-({3-[(1-methyl-1H-tetrazol-5-yl)thio]-2-oxopropyl}thio)-1H-imidazolium chloride, m.p. 196-197° C.
