Reaction Steps

A mixture of 1.4 g (5.08 mmol) of 6-chloro-2-(4-fluorophenyl)-7,8-dimethylimidazo[1,2-b]pyridazine and 8.7 g (100 mmol) of piperazine is heated at 150° C. for 3 hours in a reactor. The medium is then poured into water and the precipitate formed is isolated by filtration. The product is then recrystallized from a mixture of diisopropyl ether and isopropanol to give 1.15 g of a white powder.
