To a solution of 1.50 kg (6.35 mol) of 2,6-di-tert-butyl-4-methoxyphenol and 658 mL (6.98 mol) of acetic anhydride dissolved in 1.2 L of acetonitrile, 3 mL of conc. sulfuric acid was added and the mixture was stirred overnight at room temperature. To the mixture, a great excess of water was added and the resulting solids were filtered and dried. The obtained 4-acetoxy-3,5-di-tert-butylanisole was used in the next reaction without further purification.
