Versuchsvorschrift
To a stirring solution of 3-(hydroxymethyl)-5-isopropylphenol in 10 mL of CH2Cl2 was added 1.23 g (5.69 mmol) of PCC. The mixture was stirred for 4.5 h, Et2O was added, and the mixture was stored in a refrigerator. The solvent was concentrated, and the crude product was purified by flash silica gel chromatography (15% EtOAc/hexanes) to provide 218 mg of 3-hydroxy-5-isopropylbenzaldehyde as a pale yellow solid.
