Reaction Steps

Dissolve 3,5-di-t-butyl-4-hydroxy-aniline (2.21 g, 10 mmol) in anhydrous pyridine (25 mL) and cool to 5° C. Add, by dropwise addition, p-toluenesulfonyl chloride (2.1 g, 11 mmol) and stir overnight. Partition between water and ethyl acetate and separate the organic phase. Wash the organic phase with cold 1N hydrochloric acid, saturated sodium hydrogen carbonate and brine. Dry (MgSO4) and evaporate the solvent in vacuo to give the title compound.
