Reaction Steps

1-Phenyl-cycloheptanecarboxylic acid (R)-(1-aza-bicyclo[2.2.2]oct-3-yl)ester (Example 14e) (0.20 mmol) and 2-bromo-N-(6-methyl-pyridazin-3-yl)-acetamide (Example 49a (0.20 mmol) were stirred together in anhydrous MeCN at room temperature for 18 hours. The reaction mixture was concentrated in vacuo and the yellow solid purified by flash silica gel column chromatography eluting with 0-15% MeOH/dichloromethane to give the title compound (65 mg) as a tan solid.
