Procedure

1-Phenyl-cycloheptanecarboxylic acid (R)-(1-aza-bicyclo[2.2.2]oct-3-yl)ester (Example 1e) (61.1 mg) and 2-bromo-N-(6-trifluoromethyl-pyridazin-3-yl)-acetamide (Example 3a) (53.0 mg) were dissolved in acetonitrile (2 mL) and left overnight. The solvent was evaporated and the product was purified by column chromatography on silica eluting with 10% methanol in dichloromethane to afford the titled compound (107 mg).
