Procedure

To a solution of Intermediate tert-butyl (2S)-2-(9-chloro-3,4,5,7-tetrahydroisochromeno[3′,4′:5,6]naphtho[1,2-d]imidazol-2-yl)pyrrolidine-1-carboxylate (1.43 g, 3.0 mmol) in dichloromethane (30 mL) was added manganese(IV) oxide (15 g, 198 mmol). The mixture was stirred for four hours at room temperature then filtered through Celite. The MnO2 was thoroughly rinsed with dichloromethane and the total filtrate was concentrated to yield tert-butyl (2S)-2-(9-chloro-3,7-dihydroisochromeno[3′,4′:5,6]naphtho[1,2-d]imidazol-2-yl)pyrrolidine-1-carboxylate (1.37 g, 96% yield). This material was used without further purification.
