Reaktionsschritte

4-Benzyloxyphenol (15.00 g, 74.91 mmol) in anhydrous N,N-dimethylformamide (50 mL) was added to a solution of sodium hydride (60% dispersion in oil) (2.88 g, 74.9 mmol) in N,N-dimethylformamide (50 mL). The solution was stirred for 30 minutes and (S)-(+)-glycidyl 4-methylbenzenesulfonate (17.12, 75.0 mmol) was added. The mixture was heated to 80° C. for 2 hours. The solvent was removed and the residue partitioned between diethyl ether and water. The organic phase was washed with brine-and dried over anhydrous magnesium sulfate. The solution was filtered and the solvent evaporated to dryness in vacuo. To yield the title compound as a white solid (13.6 g, 53.3 mmol).
