Reaction Steps
1.13 g of isopropyl 2-[6-[2-(methanesulfonyloxy) ethylamino]imidazo[1,2-b]pyridazin-2-yl]-2-methylpropionate was dissolved in 15 ml of N,N-dimethylformamide; 943 mg of 4-(diphenylmethoxy)piperidine, 586 mg of potassium iodide and 488 mg of potassium carbonate were added, followed by stirring at 60° C. for 2 hours. Ice water was added; the mixture was saturated with sodium chloride and extracted with ethyl acetate; the extract was washed with saturated saline and dried with magnesium sulfate. The dry product was concentrated under reduced pressure; the residue was subjected to silica gel column chromatography and eluted with ethyl acetate:methanol (10:1). The desired fraction was collected, concentrated under reduced pressure and dried to yield 571 mg of the title compound.
