Ethyl 8-(4-cyanophenyl)-6-hydroxymethyloctanoate → Ethyl 8-(4-cyanophenyl)-6-formyloctanoate

Participants

Reaction Steps

A solution of 4 g (13.18 mmol) of ethyl 8-(4-cyanophenyl)-6-hydroxymethyloctanoate in 100 ml of dichloromethane is mixed with 3.41 g (15.82 mmol) of pyridinium chlorochromate (PCC) and stirred at room temperature for 12 hours. After conversion is complete, the solvent is concentrated to dryness in vacuo. The resulting residue is purified by flash chromatography on silica gel (mobile phase: cyclohexane/ethyl acetate 10:1→4:1). 2.74 g (9.09 mmol, 69% of theory) of a colorless solid are obtained.
