Hydrochloric Acid → 1-(6-Fluoropyridin-3-yl)ethan-1-ol

Participants

Reaction Steps

Add methyl magnesium bromide (3 M in ether, 12 mL, 36 mmol) at 0° C. under nitrogen to a solution of 6-fluoro-pyridine-3-carbaldehyde (3 g, 24 mmol) in THF (20 mL). Continue to stir the mixture for overnight at room temperature. Hydrolyze the mixture with 1 N HCl and follow the basification with diluted ammonium hydroxide to ˜pH 9. Abstract the product with chloroform/isopropyl alcohol (3/1). Dry over sodium sulfate. Concentrate the solution in vacuo to yellow oil. Purify by column chromatography (10% methanol in dichloromethane) to give the product as a colorless oil (2.3 g, 68%). MS (ES) m/z 142 [M+1]+.
