A solution of 12.02 g (32.45 mmol) of 2-(4-methylpiperidin-1-yl)ethylamine in 100 mL of DMF is combined with 17.94 g (64.82 mmol) of potassium carbonate and stirred for 15 minutes at ambient temperature. Then 5.81 g (32.45 mmol) of 3-chloro-4-fluoronitrobenzene are added and the reaction mixture is stirred for 18 hours. Then the reaction mixture is poured into ice water and the crystalline residue is filtered off. Yield: 8.85 g (91.6% of theory); C14H20ClN3O2 (M=297.78); calc.: molecular ion peak (M+H)+: 298/300; found: molecular ion peak (M+H)+: 298/300.
