实验步骤: Sodium hydride (0.17 g, 7.20 mmol) was added to a solution of 1,4-benzene dimethanol (1.00 g, 7.20 mmol) in THF at 0° C. The reaction was stirred for 1 h. 1-iodooctane (1.73 g; 7.20 mmol) was added and the reaction mixture was warmed to rt for 4 h and then heated at 50° C. for 2 days. The reaction was cooled and filtered. Silica gel chromatography eluting with 15% ethyl acetate/hexane gave 0.14 g of product: 1H NMR (500 MHz) δ 7.34-7.40 (m, 4H), 4.68-4.72 (m, 2H, 4.51 (s, 2H), 3.46-3.50 (m, 2H), 1.61-1.68 (m, 2H), 1.24-1.40 (m, 10H), 0.88-0.92 (m, 3H). heated at 50° C. for 2 days The reaction was cooled filtered Silica gel chromatography eluting with 15% ethyl acetate/hexane

The reaction mixture was stirred at room temperature for 10 minutes, after which propargyl bromide (1.0 g, 8.4 mmol) was added dropwise to the reaction mixture at 0° C. The reaction mixture was stirred at room temperature for 1 hour, after which water was added to the reaction mixture, which was extracted with ethyl acetate. The organic layer was washed and saturated aqueous sodium chloride, and was concentrated under a reduced pressure. The residue thus obtained was purified by NH silica gel column chromatography (heptane:ethyl acetate=3:2) to obtain the title compound (860 mg, 58%). The reaction mixture was stirred at room temperature for 1 hour was extracted with ethyl acetate The organic layer was washed saturated aqueous sodium chloride, and was concentrated under a reduced pressure The residue thus obtained was purified by NH silica gel column chromatography (heptane:ethyl acetate=3:2)
