Embodiment 1
[0330] 2-(4-Benzyloxyphenyl)-methyl acetate
[0331]
[0332] To a solution of (4-hydroxy-phenyl)-acetic acid methyl ester (30 mmol) in 25 mL of anhydrous dimethylformamide was added potassium carbonate (34 mmol) and 4 mL of benzyl bromide at 0 °C under nitrogen atmosphere (34mmol). The mixture was heated to 60°C for 3 hours. After cooling to ambient temperature, the reaction mixture was poured into water. The organic phase was separated and the aqueous layer was extracted with ethyl acetate. The combined organic layers were washed with brine and dried over magnesium sulfate. After removal of the solvent, the residue was purified by flash column chromatography to give the title compound as an oil. Yield: 83%. 1 H-NMR (CDCl 3 ): δ7.35-7.47(m, 5H); 7.23(d, J=8.8Hz, 2H); 6.96(d, J=8.8Hz, 2H); 5.07(s, 2H); 3.63(s, 3H) ; 3.60(s, 2H).
Embodiment 2
[0334] 2-(4-Benzyloxyphenyl)-ethanol
[0335]
[0336] A solution of 2-(4-benzyloxyphenyl)-acetic acid methyl ester (7.8 mmol) in dry ether (5 mL) was added to lithium aluminum hydride (15.8 mmol) in 25 mL of dry ether at 0 °C in the suspension. The reaction mixture was stirred overnight at ambient temperature, quenched with water and extracted with ethyl acetate. The combined organic layers were dried over sodium sulfate. The solvent was removed under reduced pressure to afford the title compound. Quantitative yield. 1 H-NMR (CDCl 3 ): δ7.28-7.47(m, 5H); 7.17(d, J=8.7Hz, 2H); 6.95(d, J=8.7Hz, 2H); 5.07(s, 2H); 3.85(t, J= 6.6Hz, 2H); 2.84(t, J = 6.6Hz, 2H).
