反応手順
In like manner to the preparation of 5-fluoro-N4-(3-hydroxyphenyl)-N2-[4-(3-phenyl-1,2,4-oxadiazol-5-yl)methyleneoxyphenyl]-2,4-pyrimidinediamine, 2-chloro-N4-(3,4-ethylenedioxyphenyl)-5-fluoro-4-pyrimidineamine and 3,5-difluoroaniline were reacted to provide N4-(3,4-ethylenedioxyphenyl)-5-fluoro-N2-(3,5-difluorophenyl)-2,4-pyrimidinediamine. 1H NMR (CDCl3): δ 7.94 (d, 1H, J=3.3 Hz), 7.20–7.11 (m, 3H), 7.02 (s, 1H), 6.92–6.90 (m, 2H), 6.65 (s, 1H), 6.39 (tt, 1H, J=2.4 and 9.0 Hz), 4.31 (s, 4H); 19F NMR (282 MHz, CDCl3): −31142, −47002; LCMS: purity: 97%; MS (m/e): 375(MH+).
