Procedure
N,N′-Bis-(3-iodo-4-methyl-phenyl)-malonamide (43.4 g, 81.3 mmol) was added portionwise to a melt of aluminum chloride (32.5 g, 244 mmol) and sodium chloride (9.50 g, 163 mmol) at 150° C., then the mixture was heated at 250° C. for 20 min. After cooling the solid formed was suspended in hot water and collected by filtration. This crude material was suspended in hot 0.5 M aq. sodium hydroxide solution, insoluble material was removed by filtration, and the filtrate was acidified with 25% aq. hydrochloric acid solution. The precipitate was collected by filtration, washed with water and ethyl acetate, and dried to afford the title compound (6.85 g, 28%). Light brown solid, EI-MS: m/e=301.2 (M+).
