Procedure
In a manner analogous to the preparation of N4-(3,4-ethylenedioxyphenyl)-5-fluoro-N2-(3-hydroxyphenyl)-2,4-pyrimidinediamine, 3-aminobenzonitrile (142 mg, 1.2 mmol) and 2,4-dichloro-5-fluoropyrimidine (100 mg, 0.6 mmol) gave 2-chloro-N4-(3-cyanophenyl)-5-fluoro-4-pyrimidineamine (128 mg, 86%) as a white solid. The reaction of 2-chloro-N4-(3-cyanophenyl)-5-fluoro-4-pyrimidineamine (50 mg, 0.2 mmol) and 3-aminophenol (66 mg, 0.6 mmol) gave N4-(3-cyanophenyl)-5-fluoro-N2-(3-hydroxyphenyl)-2,4-pyrimidinediamine (40 mg, 62%). 1H NMR (acetone-d6): 66.48 (ddd, J=0.9, 2.4 and 7.8 Hz, 1 H), 7.10 (t, J=8.1 Hz, 1 H), 7.18 (ddd, J=1.2, 2.1 and 8.1 Hz, 1 H), 7.33 (t, J=2.1 Hz, 1 H), 7.45 (dt, J=1.2 and 7.8 Hz, 1 H), 7.54 (t, J=8.1 Hz, 1 H), 8.08 (d, J=3.3 Hz, 1 H), 8.14 (ddd, J=1.5, 2.7 and 8.4 Hz, 1 H), 8.39 (t, J=2.1 Hz, 1 H), 8.58 (s, 1H, NH), 8.84 (s, 1 H, NH); 19F NMR (282 MHz, acetone-d6): δ −167.41; LCMS: ret. time: 17.75 min.; purity: 92.39%; MS (m/e): 322.59 (MH+).
