Versuchsvorschrift

In a manner analogous to the preparation of 2-chloro-N4-(3,4-ethylenedioxyphenyl)-5-fluoro-N2-(3-hydroxyphenyl)-2,4-pyrimidineamine, 2-chloro-5-fluoro-N4-(3-hydroxyphenyl)-4-pyrimidineamine and 2,3-dihydro-1,4-benzodioxin-6-ylmethylamine gave N2-(2,3-dihydro-1,4-benzodioxin-6-ylmethyl)-5-fluoro-N4-(3-hydroxyphenyl)-2,4-pyrimidinediamine. 1H NMR (CDCl3) δ 4.24 (s, 4H), 4.45 (d, J=6.0 Hz, 2H), 6.55 (ddd, J=0.9, 2.4 and 8.4 Hz, 1H), 6.66 (d, 1H), 6.84 (m, 4H), 6.90 (m, 1H), 7.14 (t, J=8.1 Hz, 1H), 7.30 (m, 1H), 7.86 (d, J=3.3 Hz, 1H); 19F NMR (282 MHz, CDCl3) δ −170.44; LCMS: ret. time: 18.33 min.; purity: 96.75%; MS (m/e): 369.03 (MH+).
