Procedure

Tert-butyl(2S,5S)-2-(9-{2-[(2S,5S)-1-(tert-butoxycarbonyl)-5-methylpyrrolidin-2-yl]-1H-imidazol-5-yl}-1,4,5,11-tetrahydroisochromeno[4′,3′:6,7]naphtho[1,2-d]imidazol-2-yl)-5-methylpyrrolidine-1-carboxylate (393 mg, 0.55 mmol) was suspended in DCM (7 mL) and activated MnO2 (1.45 g, 16.7 mmol) was added in a single portion. The reaction mixture was heated to 40° C. After stirring for 2.5 h, the mixture was cooled to rt and the slurry was filtered over celite. The filter cake was washed with copious CH2Cl2 and MeOH and the filtrate was concentrated under reduced pressure. The crude material was taken on to the next step without further purification to afford tert-butyl(2S,5S)-2-(5-{2-[(2S,5S)-1-(tert-butoxycarbonyl)-5-methylpyrrolidin-2-yl]-1,11-dihydroisochromeno[4′,3′:6,7]naphtho[1,2-d]imidazol-9-yl}-1H-imidazol-2-yl)-5-methylpyrrolidine-1-carboxylate (328 mg, 85%).
