Add 500 mL of dichloromethane to 100 g of 2,6-dichlorobenzyl alcohol followed by 117 mL of triethylamine. Cool the solution to 5° C. and add 65 mL of acetic anhydride. After 2.5 hr at room temperature, add another 10 mL of acetic anhydride, 20 mL of triethylamine and 0.5 g of 4-dimethylaminopyridine. Wash the organic layer with 1N HCl followed by saturated aqueous sodium bicarbonate and brine. Dry the organic layer (sodium sulfate) and evaporate to afford 131.5 g of the titled compound as an oil.
