Versuchsvorschrift

A mixture of 2-fluoro-5-{2-methoxy-6-[2-(4-methoxy-phenyl)-ethylamino]-pyrimidin-4-yl}-benzaldehyde oxime [860 mg, Example 26(a)] in acetic acid (10 mL) is treated with zinc powder (0.6 g, 9.2 mmol). After 1 hour at 20° C., the reaction mixture is filtered through Celite, concentrated, diluted with 1 M sodium hydroxide solution, and extracted with ethyl acetate. The extracts are dried over magnesium sulfate, filtered, and subjected to chromatography on silica gel eluting with 10% MeOH in DCM to provide the free base, which is treated with saturated HCl in EtOAc afford [6-(3-aminomethyl-4-fluoro-phenyl)-2-methoxy-pyrimidin-4-yl]-[2-(4-methoxy-phenyl)-ethyl]-amine hydrochloride [720 mg, Example 27]. LCMS: RT=1.88 minutes, MS: 383 (M+H). IC50=41 nM
