Reaction Steps

1,1-dimethylethyl[(1R)-2-({6-[(2,5-dimethylphenyl)oxy]-3-pyridinyl}amino)-1-methyl-2-oxoethyl]carbamate (Intermediate 35, 60 mg) was dissolved in 4 mL of dry dichloromethane. To this solution, at 0° C., were added dropwise 40 equivalents of TFA (0.480 mL). The reaction was stirred for 3 hours 30 at 0° C. The reaction mixture was evaporated and then purified by SCX on a 5 g cartridge. 3 CV of methanol were used first, then the residue was adsorbed on the cartridge, washed with 5 CV of methanol and desorbed with CV of methanolic ammonia (1N). Evaporation of the volatiles, afforded the title compound (49 mg)
