Reaction Steps

A mixture of (3-fluoropropyl)triphenylphosphonium bromide (15.1 g, 37.4 millimols) with THF (70 ml) was cooled down to -20° C., followed by adding t-BuOK (4.2 g, 37.4 millimols) to the mixture, stirring for one hour, dropwise adding to the mixture, a THF (100 ml) solution of trans-4-(trans-4-(2-(4-cyanophenyl)ethyl)cyclohexyl)cyclohexanecarbaldehyde (11.0 g, 34.0 millimols) so as to keep the temperature at -20° C. or lower, stirring the mixture at the same temperature for 2 hours, and treating the reaction product in the same manner as in Example 2, except that the quantity of ethyl acetate was made 500 ml, to obtain raw 4-(2-(trans-4-(trans-4-(4-fluorobutenyl)cyclohexyl)cyclohexyl)ethyl)benzonitrile (11.3 g).
