Versuchsvorschrift
To a solution of 1,1-dimethylethyl((1R)-2-methyl-1-{[(4-{[4-methyl-3-(methyloxy)phenyl]oxy}phenyl)amino]carbonyl}propyl)carbamate (Intermediate 82, 110 mg) in dry dichloromethane (3 mL), TFA (1 mL, 12.98 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 (5 g) to afford the title compound as a yellow pale solid (68 mg).
