(3-Methanesulfonylphenyl)methanol → 3-(Methylsulfonyl)benzaldehyde

Participants

Reaction Steps

A solution of [3-(methylsulfonyl)phenyl]methanol (680 mg, 3.66 mmol) in anhydrous CH2Cl2 (20 mL) was treated with PCC (1.03 g, 4.75 mmol) at room temperature for 2 hours. The solvent was removed and the residue was purified by flash column chromatography (20-60% EtOAc in hexanes) to give the product (500 mg, 74% yield). 1H NMR (300 MHz, CDCl3) δ: 3.13 (s, 3H), 7.77-7.82 (m, 1H), 8.18-8.24 (m, 2H), 8.46-8.48 (m, 1H), 10.12 (s, 1H).
