Participants

Reaction Steps

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-trifluoromethoxyphenyl)-4-pyrimidineamine gave 5-fluoro-N2-(3-hydroxyphenyl)-N4-(3-trifluoromethoxyphenyl)-2,4-pyrimidinediamine. 1H NMR (DMSO-d6): δ 9.99 (bs, 1H), 9.61 (bs, 1H), 8.21 (d, 1H, J=4.2 Hz), 7.93 (bd, 1H, J=7.5 Hz), 7.78 (s, 1H), 7.43 (t, 1H, J=8.4 Hz), 7.03 (m, 4H), 6.43 (m, 1H); 19F NMR (DMSO-d6): −16097; LCMS: purity: 85%; MS (m/e): 381 (MH+).
