Procedure

In like manner to the preparation of N4-(3-chloro-4-trifluoromethoxyphenyl)-5-fluoro-N2-(3-hydroxyphenyl)-2,4-pyrimidineamine, the reaction of 3-hydroxyaniline with 2-chloro-5-fluoro-N4-[3-(2-phenyl-1,3,4-oxadiazol-5-yl)phenyl]-4-pyrimidineamine gave 5-fluoro-N2-(3-hydroxyphenyl)-N4-[3-(2-phenyl-1,3,4-oxadiazol-5-yl)phenyl]-2,4-pyrimidinediamine. 1H NMR (CD3OD): δ 7.72 (bs, 1H), 7.96 (bd, 3H), 7.85 (m, 2H), 7.56 (m, 4H), 7.14 (d, 1H, J=2.1 Hz), 6.91 (m, 2H), 6.28 (dd, 1H, J=1.8 and 6.9 Hz); LCMS: purity: 80%; MS (m/e): 441 (MH+).
