At first, HEBP was synthesized. HBP (1.9 g), K2CO3 (2.76 g), and 2-bromoethanol (1.25 g) were mixed, and the reaction was proceeded for 24 h at 110 °C. The resultant was extracted with dichloromethane and then purified by silica gel column chromatography to provide HEBP as a white crystalline solid.Then HEBP (484 mg), zinc powder (160 mg), THF (3 mL), and TiCl4 (0.5 mL) were mixed under nitrogen atmosphere. The reaction was carried out under stirring for 12 h and then quenched by the addition of hydrochloric acid. The resultant was extracted with ethyl acetate and dried over anhydrous Na2SO4. The crude product was purified by silica gel column chromatography. HO-TPE-OH was isolated as a yellow solid.
