Reaction Steps

To a solution of 1,1-dimethylethyl {(1R)-1-methyl-2-[(6-{[4-methyl-3-(methyloxy)phenyl]oxy}-3-pyridinyl)amino]-2-oxoethyl}carbamate (Intermediate 51, 350 mg) in dry dichloromethane (7.5 mL), TFA (2.5 mL, 32.4 mmol) was slowly added and the reaction mixture was stirred for 1.5 hours at room temperature. The solvent and the excess of TFA were evaporated and the residue was purified with an SCX cartridge (10 g) to afford the title compound as a colourless oil (258 mg).
