Reaction Steps

In a like manner to the preparation of 2-chloro-N4-(3,4-ethylenedioxyphenyl)-5-fluoro-4-pyrimidineamine, 2,4-dichloro-5-fluoropyrimidine and 4-methyl-3-trifluoromethylaniline were reacted to provide 2-chloro-5-fluoro-N4-(4-methyl-3-trifluoromethylphenyl)-4-pyrimidineamine. 1H NMR (CDCl3): δ 8.10 (d, 1H, J=3.0 Hz), 7.85-7.78 (m, 2H), 7.33 (d, 1H, J=9.3 Hz), 6.96 (bs, 1H), 2.48 (d, 3H, J=1.2 Hz); 19F NMR (282 MHz, CDCl3): −17641, −44541; LCMS: purity: 97%; MS (m/e): 306 (MH+).
