Versuchsvorschrift

To a solution of 4-chloro-5-nitro-1H-pyrrolo[2,3-b]pyridine (0.182 g, 0.921 mmol) in DMF (5 mL) was added cyclohexylamine (0.55 g, 5.5 mmol). The reaction mixture was stirred at ambient temperature for about 2 h. The solvent was removed under reduced pressure and EtOAc (100 mL) and water (20 mL) were added. The layers were separated and the organic layer was washed with water (3×25 mL) and brine (20 mL), dried over anhydrous MgSO4, filtered, and concd to give N-cyclohexyl-5-nitro-1H-pyrrolo[2,3-b]pyridin-4-amine (0.20, 57%) as a brown residue: LC/MS (Table 1, Method c) Rt=1.53 min; MS m/z 261 (M+H)+.
