반응 단계

A solution of n-BuLi (83.0 mL, 133 mmol, 1.6 M in hexanes) was added to a stirred solution of 2-methylfuran (10.0 mL, 111 mmol) in THF (85 mL) at 0° C. under inert atmosphere. The reaction mixture was stirred for 4 h at room temperature then cooled to 0° C. Ethylene oxide (8.30 mL, 166 mmol) was added dropwise and the reaction mixture was allowed to warm to room temperature overnight. After quenching with saturated aqueous NH4Cl, the resulting layers were separated and the aqueous layer was extracted with Et2O (2×250 mL). The combined organic layers were dried over Na2SO4 and concentrated under reduced pressure. Distillation at atmospheric pressure (170–185° C.) gave 10.1 g (80.3 mmol, 72%) of compound 21A as a light yellow oil.
