Procedure

A solution of crude 3-cyclopropylmethoxy-4-difluoromethoxyphenyl alcohol (24.4 g) and pyridine (9.8 mL, 120 mmol) in chloroform (150 mL) under an argon atmosphere was treated with thionyl chloride (8.0 mL, 110 mmol) and the mixture was heated at reflux for 1 h. The solvent was removed, ether was added and the precipitate was removed by filtration. The filtrate was concentrated to a pale yellow oil (26 g).
