Versuchsvorschrift

280 mg (0.443 mmole) of tert-butyl 2-benzyloxycarbonylamino-3-{5-methoxy-2-methyl-6-[4-(5,6,7,8-tetrahydro-[1,8]naphthyridin-2-yl)-piperidin-1-yl]-pyrimidin-4-ylamino}-propionate in 15 ml of dichloromethane with 3 ml of trifluoroacetic acid is stirred at ambient temperature for 18 hours. 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 then poured into diisopropyl ether. 210 mg of expected product is obtained by filtration in the form of a white solid.
