The 3,6-dibromo-2-phenylazo-phenylamine (120 mg, 0.34 mmol), iodobenzene diacetate (109 mg, 0.34 mmol), and acetic acid (5 mL) were added to a 1-neck 100-mL round bottom flask. The solution was stirred for 1 h at room temperature. The solvent was reduced with a rotary evaporator and the flask was stored at −19° C. for 16 h resulting in the formation of a solid cake. Water was added to the solid cake to dissolve the acid. A crystalline solid was collected by filtration and washed with water. GC/MS confirmed the solid as the desired product. Yield: 50%.
