To a solution of 1,1-dimethylethyl((1R)-1-{[(6-{[4-methyl-3-(methyloxy)phenyl]oxy}-3-pyridinyl)amino]carbonyl}propyl)carbamate (Intermediate 64, 175 mg) in dry dichloromethane (DCM) (6 mL) TFA (2 mL, 26.0 mmol) was slowly added and the reaction mixture was stirred for 1 h at room temperature. The solvent and the excess of TFA were evaporated and the residue was purified by SCX cartridge (5 g) to afford the title compound as a colourless solid (122 mg).
