Versuchsvorschrift

To a mixture of trimethylamine-N-oxide dihydrate (408 mg, 3.67 mmol) and spiro[cyclopent-3-ene-1,3′-pyrrolo[2,3-b]pyridin]-2′(1′H)-one (622 mg, 3.34 mmol) in dichloromethane (115 mL) was added osmium tetroxide (25 uL of 2.5% solution in 2-methyl-2-propanol). After 24 h the reaction mixture was concentrated. The crude product was loaded onto a silica gel chromatography column with a minimal amount of methanol and eluted with a gradient of 5 to 20% methanol:dichloromethane to give the title compound (0.63 g). MS: m/z=221.0 (M+1).
