Reaction Steps
In 100 g of ethanol were dispersed 12.6 g (0.1 mol) of 4-hydroxythiophenol and 4.0 g (0.1 mol) of sodium hydroxide. The dispersion was heated at 70° C. for dissolution. To the solution, 16.5 g (0.1 mol) of chloromethylcyclohexylsulfide, which was separately prepared from cyclohexanethiol, formaldehyde and hydrochloric acid according to the teaching of U.S. Pat. No. 2,354,230, was added dropwise. The solution was ripened at 70° C. for 4 hours. Thereafter, the solution was cooled, combined with 50 g of water, which was extracted twice with 100 g of dichloromethane. The organic layer was concentrated in vacuum, obtaining 26 g of the crude end product. It was subject to the subsequent reaction without further purification.
