Versuchsvorschrift

To (3-phenylisoxazol-5-yl)methanol (0.9 g, 5.1 mmol) in DCM (10 mL) was added pyridinium chlorochromate (PCC) (2.1 g, 10.2 mmol) and the mixture was stirred at room temperature for 2 hours. The reaction was quenched with water, extracted with EtOAc and dried over anhydrous sodium sulfate. The solution was then concentrated under vacuum to give 3-phenylisoxazole-5-carbaldehyde as a light yellow solid (600 mg).
