Reaction Steps
2-(dimethylamino)-6-nitro-1H-benzimidazole-4-carboxylate (1.5 g) and lithium hydroxide hydrate (2.4 g) in THF—H2O (1:1, 100 mL) was stirred at 50° C. for 2 hours. THF was removed under reduced pressure, and 1N hydrochloric acid was added to the residue with stirring under ice-cooling to adjust the pH to 5. The precipitate was collected by filtration and dried under reduced pressure to obtain the titled compound (1.38 g) as yellow solid.
