반응 단계

A suspension of (1-benzenesulfonyl-5-nitro-1H-pyrrolo[2,3-b]pyridin-4-yl)-cyclohexyl-amine (10 g, 25.0 mmol) and palladium on carbon (2.7 g, 10%, wet, Degussa, E101 NE/W) in a 3:1 mixture of THF and ethanol (200 ml) was stirred under a hydrogen atmosphere (2-3 balloons) at 50° C. for 13 h. The reaction mixture was cooled to 25° C. then was filtered through Celite. The filtrate was concentrated under reduced pressure to afford crude 1-benzenesulfonyl-N-4-cyclohexyl-1H-pyrrolo[2,3-b]pyridine-4,5-diamine (9.61 g, 100%) as a rose foam. LCMS (Method G, ESI): RT=0.83 min, m+H=371.2. This material was used in subsequent reactions without additional purification or characterization.
