Versuchsvorschrift

A solution of {(R)-2-[(E)-3-(5-cyano-2-methoxy-phenyl)-acryloylamino]-3-[4-(4-fluoro-phenoxy)-piperidin-1-yl]-propyl}-carbamic acid tert-butyl ester (0.39 g, 0.71 mmol) in DCM (2 ml) is treated with 4M hydrogen chloride in dioxane (1 ml). The reaction mixture is stirred at room temperature for 1.5 hours and then the solvent evaporated. The residue is co-evaporated with ethanol (×2) to afford (E)-N-{(R)-1-aminomethyl-2-[4-(4-fluoro-phenoxy)-piperidin-1-yl]-ethyl}-3-(5-cyano-2-methoxy-phenyl)-acrylamide.HCl salt. [MH]+ 453.2.
