5-Aminobenzimidazole Chemical Properties,Usage,Production

Uses

5-Aminobenzimidazole is a useful research chemical. It inhibits gastric acid secretion in Shay-rats. Urinary metabolite of cambendazole.

Synthesis

94-52-0

934-22-5

The general procedure for the synthesis of 5-amino benzimidazole from 5-nitrobenzimidazole was as follows: 5-nitrobenzimidazole (10.0 g, 61.3 mmol) was dissolved in methanol (250 mL) and 10% Pd/C catalyst (0.40 g) was added. The hydrogenation reaction was carried out under atmospheric pressure hydrogen atmosphere for 20 hours. Upon completion of the reaction, the catalyst was removed by Celite filtration. The filtrate was concentrated under reduced pressure to give pure 5-aminobenzimidazole (yield not provided).
