Versuchsvorschrift
To a solution of tert-butyl 2-(9-chloro-1,4,5,11-tetrahydroisochromeno[4′,3′:6,7]naphtho[1,2-d]imidazol-2-yl)pyrrolidine-1-carboxylate (1.9 g, 3.96 mmol) in dichloromethane (35 mL) was added manganese(IV) oxide (17 g, 198 mmol). The reaction mixture was stirred at room temperature for 18 hours, diluted with ethyl acetate. The organics were washed with water and brine, dried (Na2SO4), and concentrated. The crude residue was purified by flash chromatography to yield tert-butyl 2-(9-chloro-1,11-dihydroisochromeno[4′,3′:6,7]naphtho[1,2-d]imidazol-2-yl)pyrrolidine-1-carboxylate (1.52 g, 81%). LCMS-ESI+: calculated for C27H26ClN3O342: 475.9; observed [M+1]+: 476.45.
