To a solution of 1,4-dichlorobenzene (294 g) in anhydrous carbon disulfide (400 ml) was added anhydrous aluminum chloride (16.0 g). To the mixture was added dropwise chlorocyclohexane (96 g) with stirring at ambient temperature during 3 hours. After the stirring was continued for 3 hours at ambient temperature, the reaction mixture was allowed to stand overnight at ambient temperature. To the reaction mixture was added dil.hydrochloric acid with stirring. The organic layer was separated, washed with water, dried over magnesium sulfate, concentrated under reduced pressure and allowed to stand at ambient temperature for a while to give precipitates. The precipitates were removed by filtration. The filtrate was distilled under reduced pressure to give 1,4-dichloro-2-cyclohexylbenzene (47.0 g).
