실험 절차
Lithium aluminum hydride (3.1 mL of 1.0 M solution in THF, 3.1 mmol) was added to a solution of methyl 3-ethylbenzoate (500 mg, 3.05 mmol) in THF (12 mL) at 0° C. After 2 h at 0° C., the reaction was quenched by the addition of saturated aqueous Rochelle's salt (50 mL) and stirred vigorously overnight at room temperature. The reaction mixture was extracted with Et2O (3×100 mL). The combined organic phase was dried (Na2SO4), filtered and concentrated in vacuo to afford (3-ethylphenyl)methanol which was shown to be ˜90% pure by 1H NMR analysis and was taken on without further purification.
