실험 절차

Allyl iodide (8.2 mL, 89 mmoles) was added to a solution of hydroquinone (7.84 g, 71.2 mmoles) and K2CO3 (19.7 g, 142.4 mmoles) in acetone (102 mmoles). The resulting mixture was heated to 40° C. overnight and concentrated under reduced pressure. The crude products were filtered through a pad of silica with 1:1 hexanes:ethyl acetate. The residue was purified by flash chromatography on a prepacked Biotage column (hexane to 1:1 hexane:ethyl acetate) on silica gel to provide the title compound (4.40 g, 41%).
