실험 절차

2-Methoxy-1-phenyl-ethanone (5.00 g) dissolved in tetrahydrofuran (50 mL) was added to 2 M allylmagnesium chloride in tetrahydrofuran (21 mL) at room temperature. The solution was stirred at room temperature for 3 h and then 10% aqueous NH4Cl solution (50 mL) was added. The resulting mixture was extracted with tert-butyl methyl ether (3×50 mL) and the combined extracts were washed with water (50 mL) and brine (50 mL). The solvent was evaporated to afford the title compound as a colorless oil. Yield: 6.40 g (quantitative). Mass spectrum (ESI+): m/z=175 [M+H−H2O]+
