Hydrochloric Acid → 1-(2-Bromo-4-fluorophenyl)propan-1-ol

Participants

Reaction Steps

Add ethylmagnesium bromide (1 M in ether, 8.37 mL, 8.37 mmol) at 0° C. under nitrogen to a solution of 2-bromo-4-fluorobenzaldehyde (1 g, 4.93 mmol) in diethyl ether (15 mL). Stir the mixture for 1 h at RT. Add water slowly followed by adjusting the mixture to acidic conditions with 2 M HCl. Extract the product with chloroform/IPA (3/1). Dry over sodium sulfate. Concentrate the solution in vacuo to a yellow oil. Purify by column chromatography (30% ethyl acetate in hexane) to give the title compound as a colorless oil (1.1 g, 96%). 1H NMR (400 MHz, CD3Cl) δ 0.99 (t, J=7.2 Hz, 3H), 1.75 (m, 2H), 4.99 (m, 1H), 7.03 (m, 1H), 7.25 (m, 1H), 7.53 (m, 1H).
