Procedure

Into a 100-mL round-bottom flask, was placed a solution of sodium sulfite (11.3 g, 89.7 mmol) in H2O/EtOH (30/15 mL). 2-Cyclopropyl-4,5-diiodo-1H-imidazole (compound 44.2, 3.8 g, 10.6 mmol) was added and the resulting solution was heated at reflux overnight. The reaction was cooled and the volatiles were removed under reduced pressure. The solids were collected by filtration to yield 1.8 g (73%) of the title compound as a light brown solid.
