Reaction Steps

Dimethylformamide (100 ml) and potassium carbonate (10 g) were added to α-(2′-hydroxybenzyl)-γ-butyrolactone (5.0 g), and (S)-glycidyl nosylate (6 g) was added. The mixture was stirred at room temperature for 2 days. The reaction mixture was concentrated under reduced pressure and water was added. The reaction mixture was extracted with ethyl acetate. The organic layer was dried over anhydrous sodium sulfate and concentrated under reduced pressure to give the title compound (6.1 g).
