Reaction Steps

A mixture of 6-chloro-3-cyano-N-(4-methoxybenzyl)-N-phenylimidazo[1,2-b]pyridazin-8-amine (25 mgs) from Example XXXI(1) step 1b, 6N NaOH (0.1 mL), MeOH (0.1 mL) and dioxane (1 mL) in a vial was heated to 100° C. for 16 h. The mixture was cooled to room temperature and concentrated in vacuo. Upon addition of 1M HCl a precipitate forms. The precipitate was collected by filtration and dried to provide 35 mgs of crude 6-chloro-8-((4-methoxybenzyl)(phenyl)amino)imidazo[1,2-b]pyridazine-3-carboxamide.
