A solution of 112 (2.1 g) in warm THF (300 mL) was treated with triethylamine (5 mL) and the solution allowed to come to room temperature. A solution of 3,4-dichlorobenzoyl chloride (2.3 g) in THF (50 mL) was added dropwise over 20 min. After stirring over night, the solvent was evaporated to give a solid (3.97 g) that had the appropriate nmr spectrum.
