Participants

Reaction Steps

After adding 0.52 g of imidazole and 1.49 ml of chlorotriisopropylsilane to a solution of 1.0 g of 3-fluoro-5-methoxy-4-hydroxybenzaldehyde [CAS No. 79418-78-3] in 15 ml of DMF, the mixture was stirred at room temperature for 17 hours. Water was added to the reaction mixture and extraction was performed with ethyl acetate. The organic layer was washed with dilute hydrochloric acid and saturated brine, and then dried over anhydrous sodium sulfate. The desiccating agent was filtered off and the filtrate was concentrated under reduced pressure. The residue was purified by silica gel column chromatography (ethyl acetate-heptane) to give the title compound (1.67 g) as a colorless oil.
