Reaction Conditions

Reaction Steps

A solution of 1-(6-hydroxybenzo[d][1,3]dioxol-5-yl)ethanone (1.5 g, 8.3 mmol) in trifluoroacetic acid (15 mL) was added with hexamethylenetetramine (1.7 g, 13 mmol), and the mixture was stirred at 40° C. for 12 hours. The reaction mixture was added with toluene, and then the solvent was evaporated under reduced pressure. The residue was dissolved in ethyl acetate, and the solution was successively washed with water, saturated aqueous sodium hydrogencarbonate, and saturated brine. The organic layer was dried over anhydrous magnesium sulfate, the solvent was concentrated under reduced pressure, and the residue was subjected to silica gel column chromatography (eluted with chloroform/methanol (100:0→97:3)) to obtain 6-acetyl-5-hydroxybenzo[d][1,3]dioxole-4-carboxaldehyde (0.11 g, 6%).
