実験手順
In a 2 dram reaction vial was added crude 6-chloro-N-(4-nitrophenyl)imidazo[1,2-b]pyridazin-8-amine (0.42 g, 1.4 mmol) from 1a and trans-1,4-diaminocyclohexane (1.0 g, 8.0 mmol). The mixture was allowed to melt at 160° C. for 8 hrs. The melt was then cooled, diluted with water and extracted with dichloromethane. The organic layer was concentrated to provide crude N6-((trans)-4-aminocyclohexyl)-N8-(4-nitrophenyl)imidazo[1,2-b]pyridazine-6,8-diamine which was used without further purification.
