Procedure

The title compound was prepared in accordance with the literature reference of Cliff & Pyne, Synthesis-Stuttgart (7), 681–682(1994) by reacting 2-cyclopropyl-1H-imidazole with iodine in the presence of NaOH. The obtained 4,5-diiodo-2-cyclopropyl-1H-imidazole was then reacted with sodium sulfite to obtain the title compound.
