실험 절차
Step C To a solution of 3-ethyl-3-methyl-pentanoic acid methyl ester (1.5 g, 9.4 mmol) in anhydrous tetrahydrofuran (30 mL) at 0° C. was added a tetrahydrofuran solution (2 M) of LiAlH4 (5 mL, 10 mmol) under nitrogen. The reaction mixture was stirred at 0° C. for 1 h, then poured into a ice-water. The mixture was extracted with ethyl acetate. The organic layer were separated, washed with water, aqueous HCl solution, brine, dried over MgSO4, and concentrated to give 3-ethyl-3-methyl-pentan-1-ol as a yellow oil (1.3 g, 100%).
