実験手順
To a solution of 3-hydroxy-4,5-dimethylisoxazole (7 g, 62 mmol) in ether (50 mL) was added diazomethane until a persistent yellow colour was obtained. The reaction was stirred for another 30 min at room temperature. The ether was evaporated off and the residue purified by column chromatography on silica gel using ether as eluent. 4 g of the desired material was obtained.
