Procedure

Into a reaction vessel were put potassium phthalimide (5.00 g, 27.0 mmol), benzyltrimethylammonium chloride (0.50 g, 2.70 mmol) and tert-buyl alcohol (50 ml) and then thereto was added (S)-epichlorohydrin (6.53 g, 54.0 mmol). The mixture was stirred at 20° C. for 24 hours and the solvent was removed. To the residue was added ethyl acetate (30 ml), the mixture was washed with water (20 ml), and then ethyl acetate was removed to give crude (S)-glycidylphthalimide (3.95 g, yield: 72%, optical purity: 97% e.e.) as a white solid.
