Reaction Steps

In a nitrogen atmosphere 3.2 g (0.01 mol) of 1-benzhydryl-2-mercapto-5-methoxycarbonyl-imidazole (Example 1a) and 60 cc of pyrrolidine were refluxed for 3 days. Excess pyrrolidine was then removed in vacuo and the 1-benzhydryl-2-mercapto-5-imidazole-carboxylic acid pyrrolidine obtained was recrystallized from methanol (m.p. 263° C.). The yield was 3.3 g (91% of the theory).
