反応手順

To the 2,6-di-tert-butylhydroquinone obtained in Example 10, 50 mL of hexane, 13.92 g (136.5 mmol) of acetic anhydride and 0.79 g (8.06 mmol) of sulfuric acid were added and the mixture was stirred for 2 hours at 50° C. The mixture was cooled to 10° C. and after adding 30 mL of water and 10 mL of ethyl acetate, the mixture was stirred overnight. The solution was subjected to liquid-liquid separation and the aqueous layer was discarded; thereafter, the organic layer was washed with 40 mL of 7.5% aqueous sodium hydrogencarbonate and 40 mL of 10% aqueous sodium chloride and the solvent was distilled off under reduced pressure to give 1,4-diacetoxy-2,6-di-tert-butylbenzene.
