Procedure

In a dry box, 2,4-di-tert-butyl-6-(5-chloro-2H-benzo-triazol-2-yl)phenol (25 g, 70.11 mmol) was transferred to a 1 L round bottom flask and dissolved in pentane (150 ml) to from a solution. Tetrakis(dimethylamino)zirconium (9.38 g, 35.05 mmol) in pentane (150 ml) was added to this solution. The mixture was stirred for one hour and then the volatiles were removed under vacuum to obtain yellow solid. The yellow solid was used without further purification (yield, 91%).
