実験手順
A mixture of 2.2 g of trans-4-(3,4-difluorophenyl)-cyclohexanecarbaldehyde (obtainable by converting the corresponding acid into the chloride and Rosenmund reduction), 1.32 g of 2-butylpropane-1,3-diol, 0.01 g of p-toluenesulfonic acid and 15 ml of toluene is boiled on a water separator for 3 hours, cooled, washed with water and evaporated, to give 2-[trans-4-(3,4-difluorophenyl)cyclohexyl]-5-butyl-1,3-dioxane.
