Procedure

120 mg (0.195 mmole) of tert-butyl 2-benzyloxycarbonylamino-3-{5-formyl-6-[4-(5,6,7,8-tetrahydro-[1,8]naphthyridin-2-yl)-piperidin-1-yl]-pyrimidin-4-ylamino}-propionate in 10 ml of dichloromethane with 1 ml of trifluoroacetic acid is stirred at ambient temperature for 24 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 with a little methanol then poured into diisopropyl ether. The precipitate is filtered. 60 mg of expected product is obtained in the form of a white solid.
