Procedure

6 g of aluminium chloride are added to 5 g of 2-chloro-5-nitrobenzoyl chloride in 60 ml of dichloromethane, and 30 ml of 1,3-dichlorobenzene are then added dropwise. The reaction medium is heated for 2 hours at 80° C. and then cooled, and poured onto crushed ice. After extracting with dichloromethane, washing with water and drying over sodium sulphate, the organic phase is evaporated to dryness under vacuum and the crystalline residue is recrystallized in cyclohexane (3.6 g).
