Procedure

5,6,7,8-tetrahydro-5,5,8,8-tetramethylnaphthalene (10.09, 53.2 mmol) and o-nitrobenzoic acid chloride (9.4 g, 50.5 mmol) were dissolved in dichloromethane (50 ml), and the mixture was added with AlCl3 (14.3 g) portionwise and then heated under reflux for 1 hour and 30 minutes. The reaction mixture was poured into water and extracted with dichloromethane and dried, and then the solvent was evaporated to give a crude product (21.59 g). This product was purified by silica gel column chromatography (AcOEt:n-hexane=1:10) to give (5,5,8,8-tetramethyl-5,6,7,8-tetrahydro-2-naphthyl)carbonyl-2-nitrobenzene (Compound 37, 7.5 9, 42%). This product was further recrystallized from n-hexane.
