p-Anisidine (12.32 g) is dissolved in 160 ml of methylene chloride and 20 g of anhydrous magnesium sulfate is added. The mixture is cooled in an ice bath and 13.22 g of transcinnamaldehyde is added. The mixture is stirred under nitrogen for 2 hours and then filtered. The filtrate is evaporated to give a solid. The crude product is recrystallized from methylene chloride-petroleum ether to give 20.96 g of the title compound as a solid.
