Procedure

To a solution of 1,1-dimethylethyl {(1R)-1-methyl-2-[(4-{[3-(methyloxy)phenyl]oxy}phenyl)amino]-2-oxoethyl}carbamate (Intermediate 1, 435 mg) in dry dichloromethane (6 mL), TFA (2 mL, 26.0 mmol) was added and the reaction mixture was stirred for 1 hour at room temperature. The solvent and the excess of TFA were evaporated and the residue was purified by SCX cartridge to afford the title compound as a yellow gum (320 mg).
