実験手順
To a solution of 1-benzenesulfonyl-5-nitro-1H-pyrrolo[2,3-b]pyridine (2.8 g, 9.24 mmol) in tetrahydrofuran (50 mL) was added 10% palladium on activated carbon (0.98 g). The resulting mixture was stirred under hydrogen (50 psi) for 48 h at room temperature. The catalyst was removed by filtration and the filtrate was concentrated to afford 1-benzenesulfonyl-1H-pyrrolo[2,3-b]pyridin-5-ylamine (2.52 g, 100%) as a yellow oil which was used in the next step without purification: LC/MS m/e calcd for C13H11N3O2S [M+H]+ 274.32, observed 274.1.
