3-CHLORO-2-HYDROXY-BENZALDEHYDE Usage And Synthesis

Chemical Properties

Yellow Solid

Uses

3-Chlorosalicylaldehyde (cas# 1927-94-2) is a compound useful in organic synthesis.

Synthesis

To a stirred solution of 2-chlorophenol (20.0 g, 155.60 mmol) in acetonitrile (200 mL) at room temperature was added MgCl 2 (22.2 g, 233.35 mmol) and triethylamine (59.03 g, 583.39 mmol). Paraformaldehyde, 0.52 g, 1.05 mol) was added to the mixture and then refluxed for 4 hours. The resulting mixture was cooled to room temperature, quenched with 2N HCl, extracted with ether, dried over MgSO4, filtered and concentrated under reduced pressure. The crude compound was purified by silica gel column chromatography to afford the title compound 3-chloro-2-hydroxybenzene.
