A mixture of (7-chloro-1H-pyrrolo[2,3-c]pyridin-2-yl)methanol (Example 1) (2.81 g, 15.4 mmol), manganese(IV)oxide (16 g) and dichloromethane (250 mL) was stirred under an atmosphere of nitrogen for 16 h. The mixture was filtered through a pad of diatomaceous earth, washing generously with hot acetone. Evaporation of the solvents provided 7-chloro-1H-pyrrolo[2,3-c]pyridine-2-carboxaldehyde (2.40 g, 13.3 mmol, 84%) as a mixture of aldehyde and aldehyde hydrate: 1H NMR (300 MHz, CD3OD) δ5.79 (1H, s), 6.65 (1H, s), 7.44 (1H, s), 7.53 (1H, d, J=5.5 Hz), 7.72 (1H, d, J=5.5 Hz), 7.85 (1H, d, J=5.5 Hz), 7.99 (1H, d, J=5.5 Hz), 10.02 (1H, s); ESI MS m/z 181 [C8H5ClN2O+H]+.
