Versuchsvorschrift
1.4 9 g of 5-bromo-2,4-dibenzyloxybenzoic acid, 40 ml of thionyl chloride and 1 drop of DMF are stirred at room temperature for 4 hours. The thionyl chloride is removed, and the residue is treated twice with dichloromethane, giving 9.4 g of 5-bromo-2,4-dibenzyloxybenzoyl chloride, which is processed further directly.
