Participants

Reaction Steps

A mixture of ethyl 1-benzyl-2H-tetrazole-5-carboxylate and ethyl 2-benzyl-2H-tetrazole-5-carboxylate (7 g; prepared as described below and still containing a little sulpholane) was dissolved in hot ethanol (100 ml) and the hot solution was treated with a solution of potassium hydroxide (2.7 g) in water (8 ml). The white solid which separated was filtered off from the hot solution and washed with ethanol to give potassium 2-benzyl-2H-tetrazole-5-carboxylate (4.64 g), m.p. 264°-267° C. [The pure salt, obtained as a hemihydrate after recrystallisation from water, had a melting point of 272°-273° C.]
