Versuchsvorschrift

4.6 g (30 mmol) of 2-mercaptobenzimidazole were initially introduced into 60 ml of dry DMF, 8.3 g (60 mmol) of K2CO3 were added, and a solution of 6.7 g (31 mmol) of α-bromo-4-toluic acid in 15 ml of dry DMF was added dropwise at room temperature. After 4 hours, a solid residue was filtered off with suction, the DMF was removed in vacuo, and the residue was taken up in aqueous hydrochloric acid at pH 2. Crystals of the title compound separated out, and these were washed with water, methanol and ether and dried.
