Versuchsvorschrift

2-Chloro-5-nitropyridine (158 mg, 1 mmol), N-methylisoamylamine (101 mg, 1 mmol), and finely ground potassium carbonate (419 mg, 3 mmol) were heated to 80° C. in 10 mL anhydrous DMF for 3.5 hrs. The mixture was diluted with EtOAc, extracted with H2O and dried over MgSO4. The EtOAc layer was filtered, evaporated to dryness to yield 220 mg. ES-MS calcd for C11H17N3O2 (m/e) 223.28, obsd 224.1 (M+H).
