YieldReaction ConditionsOperation in experiment
100% With hydrogenchloride; potassium permanganate; sodium carbonate In water Step 1004b:
Preparation of 3H-imidazo[4,5-b]pyridine-2-carboxylic Acid.
To a boiling solution of KMnO4 (0.38 g, 2.4 mmol) in water (8 mL), a boiling solution of 3H-imidazo[4,5-b]pyridin-2-ylmethanol (0.20 g, 1.4 mmol) and Na2CO3 (0.19 g, 1.5 mmol) in water (6 mL) is added.
The resulting mixture is heated at reflux for 4 hr.
The hot mixture is filtered, the filtrate is cooled to rt, and the pH adjusted to 2 using conc. HCl.
The resulting precipitate is collected by vacuum filtration to afford 3H-imidazo[4,5-b]pyridine-2-carboxylic acid in 100percent yield: MS for C7H5N3O2: m/z 164 (M+H)+.
