Methanol → potassium 2-(4-(1H-pyrazol-1-yl)phenyl)-2-methoxyacetate

참여 물질

반응 단계

To a stirred solution of 4-(1H-pyrazol-1-yl)benzaldehyde (1.3 g, 7.55 mmol) and bromoform (0.85 mL, 9.75 mmol) in MeOH (10 mL) and dioxane (10 mL) was added dropwise a solution of potassium hydroxide (2.2 g, 39 mmol) in MeOH (10 mL) over 15 minutes. Stirring was then continued for 23 hours. The mixture was filtered through Celite, rinsed through with EtOAc and concentrated under reduced pressure to yield potassium 2-(4-(1H-pyrazol-1-yl)phenyl)-2-methoxyacetate as a light yellow solid (3.2 g) that was used without further purification. See U.S. Pat. No. 7,129,238.
