Procedure

4-(7-(R)-Benzyloxycarbonylamino-8-oxo-6,7,8,10-tetrahydro-3H-2,3,9-triaza-cyclohepta[e]inden-9-yl)-piperidine-1-carboxylic acid tert-butyl ester (100 mg, 0.19 mmol) was dissolved in dichloromethane (2 mL). Anisole (100 μL, 0.92 mmol) was added to the mixture followed by methanesulfonic acid (200 μL). Reaction stirred at room temperature for 30 minutes. Mixture was diluted with diethyl ether, and the mixture stirred at room temperature for 30 minutes. Solvents were decanted off. Residue was dried in vacuo. Title compound was obtained as dark oil in quantitative yield. MS m/e (M+H)+=434.
