Potassium Bicarbonate → 5-Bromo-2-(4-methoxyphenyl)pyrazolo[1,5-a]pyridine-3-carbaldehyde

Participants

Reaction Steps

To a stirred solution of N-((5-bromo-2-(4-methoxyphenyl)pyrazolo[1,5-a]pyridin-3-yl)methylene)-N-methylmethanaminium chloride (260 mg, 0.66 mmol) in methanol (3 mL) was added a 3% solution of potassium bicarbonate (3.1 mL) and the mixture was stirred at room temperature for 2 h. The solids were collected by filtration and dried under reduced pressure to afford the title compound as a solid (201 mg, 92%). LCMS m/z 331.0, 333.0 (M+H)+, ret. time=2.13 min.
