Reaction Steps

6-bromo-4-methoxypyrazolo[1,5-a]pyridine (1.50 g, 6.61 mmol) was suspended in HBr (15 ml, 133 mmol). The reaction mixture was heated in the Biotage Initiator Series microwave for 80 minutes at 150° C. The reaction mixture was added dropwise via pipette to a mixture of NaOH (5.29 g, 132 mmol) in 50 mL of water and ice. The mixture was diluted in ethyl acetate, washed with saturated aqueous sodium bicarbonate and brine then dried over sodium sulfate, filtered and concentrated to give 6-bromopyrazolo[1,5-a]pyridin-4-ol.
