Method CS-CG-lodo-pyridazin-S-vD-Q-methyl-Q-aza-bicvclofS.S.I Inonane free base(Intermediate Compound) A mixture of 9-methyl-3,9-diazabicyclo[3.3.1]nonane (4.0 g, 28.5 mmol), 3,6-diiodopyridazine (9.5 g, 28.5 mmol), diisopropylethylamine (7.4 g, 57.0 mmol) and dioxane (50 ml) was stirred at 75C for 4 days. Aqueous sodium hydroxide (75 ml, 1 M) was added, dioxane was evaporated and the mixture was extracted twice with dichloromethane (2 x 75 ml). Chromatography on silica gel with dichloromethane, 10% methanol and 1 % aqueous ammonia as solvent gave the title compound. Yield 4.61 g (47%). Mp 163-166C.
