Reaktionsschritte

To a solution of 4-fluoro-N-methyl-2-nitrobenzamide (Intermediate 3L) (0.65 g, 3.3 mmol) in dimethylsulfoxide (50 mL) was added 1,4-diazabicyclo[3.2.2]nonane (0.62 g, 4.9 mmol) and potassium carbonate (1.36 g, 9.8 mmol). The resulting suspension was heated at 90° C. for 4 days. The mixture was filtered and the filtrate purified using a 20 g SCX cartridge to afford 4-(1,4-diazabicyclo[3.2.2]nonan-4-yl)-N-methyl-2-nitrobenzamide (0.8 g, 2.7 mmol).
