実験手順
To a solution of 5-hydroxy-2H-pyrazole-3-carboxylic acid methyl ester (2.3 g, 16 mmol) in DMF (10 mL) at room temperature was added cesium carbonate (5.27 g, 16 mmol) and methyl iodide (2.3 g, 1.0 mL, 16 mmol) and the resulting mixture stirred for 2.5 h. The mixture was then filtered off to afford the title compound (434 mg, 17%) as a white solid after trituration with ethyl acetate. MS: m/e=157.2 [M+H]+.
後処理
