32.5 g of 4-methylbenzenesulfonyl chloride are added, at room temperature, to a solution of 34 g of Z-1-hydroxymethyl-1-(4-fluorophenyl)-2-(3-cyclohexenyl)ethene in 200 ml of methylene chloride and 29 g of triethylamine. After 24 hours, the reaction mixture is washed with aqueous sodium bicarbonate solution and water, dried over sodium sulfate and evaporated down under reduced pressure. 49.7 g (95%) of Z-1-(4-methylphenylsulfonyloxymethyl)-1-(4-fluorophenyl)-2-(3-cyclohexenyl)-ethene are obtained from the residue.
