Versuchsvorschrift
1,1-dimethylethyl[1,1-dimethyl-2-({4-[(3-methyl-1,2-benzisoxazol-4-yl)oxy]phenyl}amino)-2-oxoethyl]carbamate (Intermediate 24, 34 mg) was dissolved in 4.0 ml of dichloromethane and then TFA (1.0 ml) was added. The reaction mixture was stirred at room temperature for 1 hour. After removal of the volatiles, the residue was charged on a SCX cartridge and eluted successively with dichloromethane, MeOH, NH3 (2.0 M solution in MeOH). Evaporation afforded 18 mg of the title compound.
