Procedure

To 3-(3-nitro-benzyl)-5-pyridin-3-yl-1-(toluene-4-sulfonyl)-1H-pyrrolo[2,3-b]pyridine (552, 230 mg, 0.14 mmol) in methanol (5 mL) was added 10% palladium on carbon (10 mg) and few drops of concentrated aqueous hydrochloric acid. The resulting mixture was stirred under an atmosphere of hydrogen overnight, and the catalyst was filtered out through a bed of celite. The filtrate was concentrated and purified by silica gel column chromatography eluting with 90% ethyl acetate in hexane to give the compound (553, 88 mg, 41%). MS (ESI) [M+H+]+=455.3.
