A solution of 22.69 g (110 mmol, 1.1 equivalents) of 2,6-di-t-butylphenol in 10 mL of toluene was treated with 100 mL (100 mmol) of a 1M solution of tetrabutylammonium hydroxide in methanol under nitrogen with stirring at ambient temperature. The resulting dark green solution was stirred for 1 hour and concentrated under vacuum to a thick residue. Two 100 mL portions of toluene were added and removed by evaporation under vacuum yielding 52.08 g of wet, crude title compound as a green solid which was used in the next step without further purification.
