6-Bromo-4-methoxypyrazolo[1,5-a]pyridine Use and Manufacturing
6-Bromopyrazolo[1, 5-ajpyridin-4-ol (0.5 g, 2.35 mmol) in DMF (5 mL) under an atmosphere of nitrogen was added cesium carbonate (2.3 g, 7.04 mmol), followed by methyl iodide (0.22 mL, 3.52 mmol) and the reaction was heated at 80 °C for 1 h. The reaction was cooled at rt, diluted with ethyl acetate, washed with water several times, washed with brine, dried over sodium sulfate, and concentrated. The product was purified via silica gel chromatography (1 0percentethyl acetate/hexanes) and concentrated. 6-Bromo-4-methoxy-pyrazolo [1 , 5-ajpyridine was isolated as a solid (0.43 g, 80percent). Analysis: LCMS m/z = 228 (M+1).Step B: DecarboxylationA solution of ethyl 6-bromo-4-methoxylpyrazolo[l, 5-a]pyridine-3-carboxylate (15, 5.2 g, 18.24 mmol) in HBr (100 ml, 884 mmol) was heated to 100
