Reaction Steps

To a solution of 1,1-dimethylethyl ((1R)-1-{[(2-{[3-(ethyloxy)-4-methylphenyl]oxy}-5-pyrimidinyl)amino]carbonyl}propyl)carbamate (Intermediate 93, 80 mg) in dichloromethane (1 mL) cooled to 0° C., TFA (573 μl, 7.43 mmol) was added dropwise. The mixture reaction was stirred at 0° C. for 1.5. The solvent and the TFA were evaporated. The mixture was diluted with dichloromethane and an aqueous saturated solution of NaHCO3. The organic layer was separated, dried over sodium sulphate, filtered end evaporated to afford the title compound (65 mg) which was directly used in the next step.
