Potassium Hydroxide → (S)-2-((R)-2-(4-fluorophenyl)-2-hydroxyethyl)hexanoic acid

Participants

Reaction Steps

To the solution of (3S,5R)-3-butyl-5-(4-fluorophenyl)dihydrofuran-2(3H)-one (94.0 mg, 0.40 mmol) in 5 mL dioxane was added 5 mL aqueous 5% KOH at 25° C. After being stirred for 30 min at room temperature the reaction was quenched by the addition of 6 mL of 1M aqueous HCl. The mixture was extracted ethyl acetate (2×10 mL) and the combined organic layers were washed with brine (2×10 mL) before being concentrated under reduced pressure. The crude product was used directly in the next reaction without further purification.
