Procedure

To a solution of 2,4,6-trimethoxystyryl-3-amino-4-methoxybenzylsulfone (10 mmol) in methanol (40 mL) is added 4-nitrobenzaldehyde (10 mmol). The solution is refluxed with vigorous stirring for 5 h. The reaction mixture is cooled, diluted with water and the aqueous mixture is then extracted twice with dichloromethane and organic layer is dried over anhydrous magnesium sulfate. The dried organic solution is evaporated and the residue is recrystallized to give (E)-2,4,6-trimethoxystyryl-3-(4-nitrophenylimino)-4-methoxybenzylsulfone.
