Participants

Reaction Steps

In 100 ml of methylene chloride was dissolved 2 g of 2-(p-chlorophenyl)imidazo[2,1-b]benzothiazole and after adding thereto 20 ml of an aqueous 10% potassium hydrogencarbonate solution and 1.8 g of iodine, the mixture was stirred overnight vigorously at room temperature. The crystals which formed were recovered by filtration and recrystallized from a mixture of methylcellosolve and water to provide 2.4 g of 2-(p-chlorophenyl)-3-iodoimidazo[2,1-b]benzothiazole.
