실험 절차
1,1-dimethylethyl{(1R)-1-methyl-2-[(6-{[3-(1-methylethyl)phenyl]oxy}-3-pyridinyl)amino]-2-oxoethyl}carbamate (Intermediate 25, 56 mg) was dissolved in 3 mL of dry dichloromethane. To this solution at 0° C. were added dropwise 30 equivalents of TFA (0.324 mL). The reaction was stirred at 0° C. for 3 hours. The reaction mixture was evaporated. The crude obtained was 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 2 CV of methanolic ammonia (1N). Evaporation of the volatiles, afforded the title compound (38 mg).
