Procedure

To a solution of 115 (550 mg, 2.31 mmol) in acetonitrile (5 mL) was added cyanogen bromide (489 mg, 4.6 mmol). The reaction flask was covered with aluminum foil and the mixture was allowed to stir at room temperature for 18 h. The solvent was removed under reduced pressure and the residue was purified by column chromatography (eluents 100% EtOAc to 30% MeOH/EtOAc), to afford title compound 116 as a beige solid (230 mg (31%). MS (m/z) 317.1/319.1 (M+H).
