Reaction Steps

To a solution of (E)-1-cyclohexyl-3-(5-tosyl-5H-pyrrolo[2,3-b]pyrazin-2-yl)prop-2-en-1-one (0.050 g, 0.12 mmol) in EtOAc (5 mL) was added palladium (10% on carbon, 0.0065 g, 0.0061 mmol). The reaction mixture was purged with hydrogen and a hydrogen atmosphere was maintained via balloon. After about 1 h at ambient temperature, the reaction mixture was filtered and concentrated under reduced pressure to provide 1-cyclohexyl-3-(5-tosyl-5H-pyrrolo[2,3-b]pyrazin-2-yl)propan-1-one as an oil (0.050 g, 100%): LC/MS (Table 2, Method a) Rt=2.94 min; MS m/z: 412 (M+H)+.
