실험 절차

To a mixture of AlCl3 (13 g, 97.5 mmol, 1.0 equiv) in benzene (100 mL) kept at 35° C., was added 1-cyclohexenecarboxylic acid (5 g, 39.7 mmol, 0.41 equiv) dropwise. After addition was complete, the reaction solution was heated to 70° C. for 1 h and 45° C. overnight. The reaction was cooled, and 200 mL of 1 N HCl was slowly added. The product was extracted with EtOAc. The organic layer was extracted with 1 N NaOH and the aqueous layer was acidified with concentrated HCl to produce a white precipitate that was collected by filtration, washed with water and dried to give the titled compound as a white solid (3.1 g, 38%) which was used without further purification.
