Reaktionsschritte

To a stirred solution of benzyl 3-bromo-5-hydroxybenzoate (2.85 g, 9.22 mmol) in dimethyl formamide (50 mL), was added 2-(8-bromooctyl)-1,3-dioxolane (2.44 g, 9.21 mmol) and potassium carbonate (1.91 g, 13.8 mmol), and the mixture stirred at 80° C. for 16 hours. The reaction mixture was cooled to room temperature, diluted with water and extracted with ethyl acetate (×3). The combined organic extracts were washed with brine, dried (magnesium sulphate), filtered, and concentrated under reduced pressure. The crude material was purified by silica gel chromatography eluting with 0-7% ethyl acetate in iso-hexane to afford the title compound (2.94 g, 65%).
