Participants

Reaction Steps

16 g (0.039 mol) of 5-biphenyl-4-yl-2-phenyl-5,6-dihydrophenanthridine are dissolved in 300 ml of dichloromethane. and 62.13 g (0.393 mol) of potassium permanganate are added in portions to this solution, and the mixture is stirred at room temperature for two days. After this time, the remaining potassium permanganate is filtered off, the solution is evaporated and purified by chromatography (eluent: heptane/dichloromethane, 5:1). The residue is recrystallised from n-heptane. The yield is 14 g (88%).
