To a solution of (E) 3-(5,6-dichloroindol-2-yl)-2-propen-1-ol (23.8 g, 98.3 mmol) in diethyl ether (800 ml) activated MnO2 (71 g, 8.76 mol) and NaCl (60 g) were added and the resulting suspension stirred for one day at RT. It was then filtered on a Celite pad repeatedly washed with AcOEt and the organic phase dried (MgSO4) and evaporated to give 21.0 g of the title compound (87.5 mmol, yield 89.0%) that was used as such in the next step.
