Procedure

Safrole oxide was prepared by stirring a solution of safrole (1.48 mL, 10 mmol) and m-chloroperoxybenzoic acid (2.70 g, 11 mmol) in methylene dichloride (25 mL) overnight. The reaction was quenched by pouring into water (50 mL). The aqueous was extracted with ether (3×25 mL). The organic layers were combined and washed with 10% aqueous sodium sulfate (2×25 mL), saturated aqueous sodium bicarbonate (3×25 mL), and brine (25 mL). The organic phase was dried over magnesium sulfate and the solvents were removed in vacuo. The resulting yellow oil was used without further purification.
