Reaction Steps

To 6.25 g of 4-acetoxy-3-t-butylphenol dissolved in 15 ml of trifluoroacetic acid was added 4.63 g of hexamethylenetetramine and the mixture was heated under reflux for 1 hour. The reaction mixture was allowed to attain room temperature, then poured into water and extracted with ethyl acetate. The organic layers were successively washed with a 1N aqueous sodium hydroxide solution, water and saturated brine, dried over anhydrous magnesium sulfate and concentrated. The concentrate was purified by silica gel column chromatography (in n-hexane containing 20% ethyl acetate) to give 3.68 g of 5-acetoxy-4-t-butyl-2-hydroxybenzaldehyde as a pale yellow oil (52%).
