Procedure

In a manner analogous to the preparation of N2,N4-bis(3-hydroxyphenyl)-5-fluoro-2,4-pyrimidinediamine, the reaction of 3-hydroxy-2-methylaniline (369 mg, 3 mmol) and 2,4-dichloro-5-fluoropyrimidine (100 mg, 0.6 mmol) gave N2,N4-bis(3-hydroxy-2-methylphenyl)-5-fluoro-2,4-pyrimidinediamine (180 mg, 88%). 1H NMR (acetone-d6): δ 2.14 (s, 3 H), 2.22 (s, 3 H), 6.61 (d, J=8.1 Hz, 1 H), 6.78 (t, J=8.7 Hz, 1 H), 6.87 (d, J=7.8 Hz, 1 H), 6.99 (d, J=9.0 Hz, 1 H), 7.08 (t, J=7.8 Hz, 1 H), 7.13 (dd, J=3.9, 8.4 Hz, 1 H), 8.24 (d, J=5.1 Hz, 1 H), 8.32 (br, 1 H, NH), 8.57 (br, 1 H, NH); LCMS: ret. time: 16.51 min.; purity: 90.47%; MS (m/e): 341.07 (MH+).
