合成路线图解说明: 3-Benzyl-3,8-diazabicyclo[3.2.1]octane (I) was protected at the N8 position with di tert-butyl dicarbonate in CH2Cl2, and carbamate (II) was then debenzylated by catalytic hydrogenolysis over Pd/C. The resulting bicyclic amine (III) was condensed with 3,6-dichloropyridazine (IV) in the presence of Et3N to give the Boc-protected intermediate (V), which was finally deprotected with HCl in Et2O.
