Versuchsvorschrift
To a stirred and cooled (ice-bath) mixture of 22 parts of 2,4-dichloro-β-(cyclohexylmethyl)benzeneethanol and 50 parts of pyridine are added dropwise 8.8 parts of methanesulfonyl chloride. Upon completion, stirring is continued for 3 hours at room temperature. The reaction mixture is poured onto water and the product is extracted twice with trichloromethane. The combined extracts are washed twice with a diluted hydrochloric acid solution and once with water, dried, filtered and evaporated. The residue is crystallized from 2,2'-oxybispropane, yielding 16.5 parts of 3-cyclohexyl-2-(2,4-dichlorophenyl)propyl methanesulfonate; mp. 105.1° C.
