YieldReaction ConditionsOperation in experiment
40% Na2CO3 (3.3 g, 1 eq, 31.5 mmol) and water (200 ml) are added to product 7- methyl-3H-imidazo[4,5-b]pyridine x176 (4.2 g, 31.5 mmol). The reaction mixture is heated until boiled, which caused its transformation into a solution. KMnθ4 (12.5 g, 2.5 eq, 78.9 mmol) is added in small portions to the obtained boiling solution. After KMnθ4 is added completely, the reaction mixture is additionally kept at 100 0C for 1 h and cooled to 50- 60 0C. Mnθ2 is filtered off, and the residue is additionally washed with hot water (2 x 50 ml) on a filter. The obtained aqueous solution is evaporated in vacuum to a volume of 50 ml, cooled to 5 0C, and acidified with 10 % HCI to pH 2-3. The obtained suspension is kept at 5 0C for 1 h. The formed precipitate is separated by filtration, washed with ice-cold water (2 x 10 ml), and vacuum-dried (1 mm Hg) over P2O5 overnight to give 2.06 g of 3H- imidazo[4,5-b]pyridine-7-carboxylic acid x177.Yield: 40 %.LC-MS (MH+): 164.
