Versuchsvorschrift

45 mg (0.073 mmole) of (1,1-dimethylethyl) 3-[[5-ethyl-6-[4-(1,2,3,4-tetrahydro-1,8-naphthyridin-7-yl)-1-piperidinyl]-4-pyrimidinyl]amino]-N-(2-benzothiazolyl)alaninate in 10 ml of dichloromethane with 1 ml of trifluoroacetic acid is stirred at ambient temperature until the starting product disappears according to TLC (silicagel, eluent: CH2Cl2-MeOH—H2O—AcOH 90-10-1-1). Toluene is added and the reaction mixture is evaporated to dryness under reduced pressure (2 kPa). The residue is solubilized in the minimum amount of dichloromethane with a little methanol then poured into diisopropyl ether. The precipitate is filtered. 60 mg (Yield=97% expressed as ditrifluoroacetate) of expected product is obtained in the form of a white solid.
