Participants

Reaction Steps

To a solution of 2.0 g of 3-ethynyl-5-hydroxybenzaldehyde [CAS No. 871345-34-5] in 20 ml of DMF there were added 1.87 g of imidazole and 4.4 ml of chlorotriisopropylsilane. The mixture was stirred overnight at room temperature. Water was added to the reaction mixture and extraction was performed with ethyl acetate. The organic layer was washed with ice-cooled 1N hydrochloric acid, water and saturated brine, and dried over anhydrous magnesium 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 (3.92 g) as a light yellow oil.
