Versuchsvorschrift

To a solution of ammonium chloride (3.00 mmol) in H2O (5 ml) was added iron powder (1.66 mmol) followed by a solution of 1,1-dimethylethyl 4-{5-[4-[1-methyl-3-(4-nitrophenyl)-1H-pyrazol-4-yl]-1-(phenylsulfonyl)-1H-pyrrolo[2,3-b]pyridin-2-yl]-2-pyrimidinyl}-1-piperazinecarboxylate (0.333 mmol) in methanol (10 ml). The resulting mixture was heated at 70° C. for 2 hours, the hot solution filtered through a pad of celite 545 and concentrated to yield the title product as a yellow solid (quant.) which was used crude in the next step. ESMS [M+H]+: 692.2.
