37.7 g (0.1 mol) of the 4-diphenylamino-4'-methoxystilbene prepared in Synthesis Example 1-1 was dissolved in 250 ml of dioxane. To the thus obtained mixture, 4 g of 5% Pd/C powder and then 2.4 l of hydrogen were added. A solvent was distilled away from the reaction mixture, whereby 1-(4-diphenylaminophenyl)-2-(4-methoxyphenyl)ethane was obtained as an oily transparent compound of light yellow in color.
