Reaction Steps

Dissolve cyclohexanecarbonyl chloride (2 g, 13.6 mmol) in anhydrous toluene (30 mL). Cool the solution to 0° C., add aluminum trichloride (2.72 g, 20.46 mmol) in three portions and stir the reaction mixture at ambient temperature overnight Cool to 0° C., add slowly water and extract the mixture with EtOAc. Dry the organic layer over Na2SO4, filter and concentrate in vacuo. Purify the crude mixture by chromatography on silica gel eluting with hexane and hexane/EtOAc (19:1) to give the desired intermediate (2.75 g, 100%).
