The mixture was evaporated in vacuo. The crude product was dissolved in methylene chloride (25 ml) and water (25 ml) and 1N hydrochloric acid (1 ml) was added. The water phase was extracted with methylene chloride (2×15 ml). The combined organic phase was dried over magnesium sulphate, filtered and evaporated in vacuo giving 700 mg of the crude product. The product was recystallised in acetone/pentane to give white crystals of N-[2-(3,4-dicyanophenoxy)phenyl]-3-nitrobenzamide (yield: 650 mg (81%)). Mp: 176.5-178.1° C.
