Hydrochloric Acid → 1,1-Diphenylbutane-1,4-diol

Participants

Reaction Steps

60 ml (120 mmol) of 2 M solution of phenyl magnesium bromide in THF was added dropwise to 4.33 g (50.3 mmol) of γ-butyrolactone in 60 ml of THF for the duration of 50 minutes. After stirring at room temperature overnight, a saturated aqueous ammonium chloride solution and then 2 N hydrochloric acid were added dropwise to the reaction mixture. After the extraction with ethyl acetate, the organic layer was dried over anhydrous sodium sulfate and concentrated under reduced pressure to obtain the title compound.
