Procedure

Dissolve 2,2-dimethylphenethyl alcohol (118.0 g, 0.786 mol) in pyridine (700 mL). Add, by dropwise addition, acetic anhydride (222 mL, 240.7 g, 2.358 mol) and stir overnight at room temperature. Evaporate the solvent in vacuo and purify by distillation to give the title compound as a clear colorless oil; bp 75° C. @0.4 mmHg.
