Versuchsvorschrift
Solid pyridinium dichromate (5.4 g., 15.5 mmol) was added in portions over 8 hours to a stirred solution of 7-benzyloxyindole-4-methanol (1.17 g, 4.6 mmol) in dichloromethane (30 ml). The dark mixture was stirred for a further 2 hours, filtered through a bed of silica and evaporated.
