Ammonium Chloride → 8-(5'-Fluoro-2'-methoxyphenyl)oct-1-en-5-ol

Participants

Reaction Steps

To a solution of 4-(5′-fluoro-2′-methoxyphenyl)butyraldehyde (1.30 g, 6.6 mmol) in THF (15 mL) at 0° C. was added a solution 1-butenylmagnesium bromide (0.5 M in THF, 15 mL, 7.5 mmol) dropwise for 5 min. Then the reaction mixture was poured to a solution of saturated ammonium chloride (60 mL) in a separatory funnel. The organics were extracted with ethyl acetate (3×50 mL) and the combined organic layers were washed with brine (40 mL) and dried over sodium sulfate. The solvent then was removed in vacuo and crude product thus obtained was purified by a flash column chromatography (12.5% EtOAc in hexane, Rf=0.15) to give the product as a colorless oil (1.06 g, 61%).
