Procedure

(R)-benzyl 9-(1-acetylpiperidin-4-yl)-8-oxo-3,6,7,8,9,10-hexahydroazepino[3,4-e]indazol-7-ylcarbamate (38 mg, 0.08 mmol) was dissolved in dichloromethane (1 mL). Anisole (30 μL, 0.27 mmol) was added to the mixture followed by methanesulfonic acid (250 μL). Reaction stirred at room temperature for 2 hours. Mixture was diluted with diethyl ether. Mixture sat at room temperature for 30 minutes. Solvents were decanted off. Remaining residue was dried in vacuo. Title compound was obtained as dark oil in quantitative yield. MS m/e (M+H)+=342.
