実験手順
Step D To a solution of 3-methyl-3-(5-methyl-furan-2-yl)-butyric acid methyl ester (1.5 g, 7.8 mmol) in anhydrous tetrahydrofuran (50 mL) at 0° C. was added a tetrahydrofuran solution (1 M) of LiAlH4 (10 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-methyl-3-(5-methyl-furan-2-yl)-butan-1-ol as a yellow oil (1.2 g, 77%).
