Imidazo(1,2-b)pyridazine, 6-chloro- → Sodium 2-[(imidazo[1,2-b]pyridazin-6-yl)thio]ethanesulfonate

Participants

Reaction Steps

To a solution of 1.35 g of 6-chloroimidazo[1,2-b]pyridazine in 30 ml of methanol were added 1.45 g of sodium 2-mercaptoethanesulfonate and 1.80 ml of 28 W/W/% sodium-methanol solution, followed by refluxing for 5 hours. The precipitated crystals were collected by filtration and washed with methanol to obtain 1.98 g of sodium 2-[(imidazo[1,2-b]pyridazin-6-yl)thio]ethanesulfonate.
