To a solution of 5-fluoro-N-(2-(isopropylamino)-2-oxoethyl)-2-nitrobenzamide (Intermediate 2A) (7.39 g, 26.1 mmol) in acetonitrile (240 mL) was added potassium carbonate (14.6 g, 104 mmol) followed by 1,4-diazabicyclo[3.2.2]nonane dihydrochloride (5.45 g, 27.4 mmol). The resulting suspension was heated to reflux at 96° C. overnight. The reaction mixture was filtered and concentrated. Sample was diluted in methanol (100 mL) and split between two 20 g SCX cartridges. Purification by SCX and evaporation to dryness afforded 5-(1,4-diazabicyclo[3.2.2]nonan-4-yl)-N-(2-(isopropylamino)-2-oxoethyl)-2-nitrobenzamide (7.0 g, 18.0 mmol).
