100 mg (0.26 mmol) of N-[3-(1,1,2,2-tetrafluoro-ethoxy)-phenyl]-4-(2-cyano-4-pyridyl)-2-pyrimidineamine and 1.28 ml (1.0M in THF, 1.28 mmol) of diisobutylaluminium hydride/THF solution are stirred for 1 h at -20°. After the addition of 2 ml of methanol, the reaction mixture is heated to RT and the reaction product is isolated by filtration. After concentration under reduced pressure using a rotovapor and chromatography [methylene chloride:methanol:ammonia (conc.)=95:5:]N-[3-(1,1,2,2-tetrafluoro-ethoxy)-phenyl]-4-(2-aminomethyl-4-pyridyl)-2-pyrimidineamine is obtained; m.p. 64°-67°, FAB-MS: 394 (M+ +H).
