Reaction Conditions

Reaction Steps

To a stirred solution of 2-(5-bromopentyl)-1,3-dioxolane (4.38 g, 19.6 mmol) in dimethyl formamide (30 mL) was added 4-hydroxybenzaldehyde (3.00 g, 24.4 mmol) and potassium carbonate (4.52 g, 32.8 mmol). The reaction mixture was stirred at 50° C. for 16 hours. The reaction mixture was diluted with water and extracted with ethyl acetate (×3). The combined organic extracts were washed with saturated aqueous sodium hydrogen carbonate solution and brine, dried (sodium sulfate), filtered and concentrated under reduced pressure to afford an oil. The crude material was purified by silica gel column chromatography eluting with 0-100% ethyl acetate in iso-hexane to afford the title compound (1.92 g, 36%).
