2-(2-Chloro-5-(hydroxymethyl)phenyl)ethanol → 4-Chloro-3-(2-hydroxyethyl)benzaldehyde

Participants

Reaction Steps

Manganese (IV) dioxide (1.00 g) was added to a solution of 2-(2-chloro-5-(hydroxymethyl)phenyl)ethanol [Aromatic Intermediate 1, step b] (0.205 g) in DCM (10 mL), and the resulting suspension was stirred at room temperature overnight. The mixture was then filtered through Celite, washing the filter pad well with DCM. The filtrate and washings were concentrated under reduced pressure to afford the titled compound as a colourless oil. Yield 0.159 g.
