Procedure

A solution was prepared by combining 11.3 g of 4-hydroxyphenyl phenyl sulfide which had been synthesized according to the well-known formulation, 8.2 g of bromocyclopentane, 7.6 g of potassium carbonate, and 40 g of DMF. The solution was aged at 80° C. for 16 hours. The aged solution was cooled to room temperature, to which 100 g of 5 wt % dilute hydrochloric acid was added to quench the reaction. To the solution, 150 g of toluene was added for extraction. The organic layer was separated and washed with water. It was combined with 5 wt % sodium hydroxide aqueous solution. The organic layer was separated and washed with water again. On subsequent concentration in vacuum, 13.8 g of the target compound, 4-cyclopentyloxyphenyl phenyl sulfide was obtained as oily matter. Yield 100%.
