Procedure

11 g of NaOH (32%) are added to a solution of 8.2 (lacuna) of the resultant p-(trans-4-ethoxycyclohexyl)-o-fluorophenol in 80 ml of THF and 13.8 g of chlorodifluoromethane are introduced (dry ice reflux condenser). After subsequently stirring for one hour, the solution is decanted off from the precipitate and concentrated to give a residue. Bulb tube distillation gives p-(trans-4-ethoxycyclohexyl)-o-fluorodifluoromethoxybenzene, b.p.1 ~220° C., Tg -62°.
