실험 절차

To a suspension of 4-chloro-3-nitro-1H-pyrrolo[2,3-b]pyridine (57 mg) in 2-propanol (180 μl) were added N-methylcyclohexanamine (154 μl) and N,N-diisopropylethylamine (50 μl), and irradiated microwave at 120° C. for 15 minutes. The reaction mixture was purified by flash column chromatography over silica gel with a EtOAc/methanol (100:0-60:40) as eluant. then by preparative silica gel thin-layer chromatography with EtOAc as eluant to give a solid. The solid was washed with diisopropyl ether to give N-cyclohexyl-N-methyl-3-nitro-1H-pyrrolo[2,3-b]pyridin-4-amine (7.9 mg) as a yellow solid.
