Sulfuryl chloride → HCID 12831510, compound

Participants

Reaction Steps

To a solution of 2 g of 2-(p-chlorophenyl)imidazo[2,1-b]benzothiazole in 40 ml of methylene chloride was added a solution of 0.95 g of sulfuryl chloride in 5 ml of methylene chloride and after stirring for 10 minutes, 40 ml of an aqueous 10% potassium hydrogencarbonate solution was added to the mixture followed by stirring. The organic layer which formed was recovered, washed with water, dried with anhydrous magnesium sulfate, and concentrated under reduced pressure to form crystals, which were recrystallized from ethanol to provide 1.4 g of 3-chloro-2-(p-chlorophenyl)imidazo[2,1-b]benzothiazole.
