A mixture of 2-chloro-6-nitroquinoline (5.0 g, 24 mmol, Example 1, Step B), 2-azabicyclo[2.2.2]octane p-toluenesulfonic acid salt (10.2 g, 36 mmol) and sodium bicarbonate (5.1 g, 60 mmol) were mixed in absolute ethanol (100 mL) and then heated at reflux for 24 h. The reaction mixture was cooled to r.t., and the solvent removed under vacuum. The solids were taken up in EtOAc (750 mL). The mixture was transferred to a separatory funnel washed with water (3×100 mL) then brine (100 mL). The organic layer was dried over sodium sulfate, filtered and the solvent removed under vacuum to afford the product as a yellow solid, MS: m/z 284 (MH+) which was used without further purification.
