Reaction Steps
In like manner to the preparation of N2,N4-bis(3-hydroxyphenyl)-5-fluoro-2,4-pyrimidinediamine, 2,4-dichloro-5-fluoropyrimidine and 4-methoxyaniline were reacted to yield N2,N4-bis(4-methoxyphenyl)-5-fluoro-2,4-pyrimidinediamine. 1H NMR (CD3OD): δ 7.67 (d, 1H, J=4.8 Hz), 7.43 (d, 2H, J=9.3 Hz), 7.67 (d, 2H, J=8.7 Hz), 6.87 (d, 2H, J=9.6 Hz), 6.83 (d, 2H, J=8.7 Hz), 3.83 (s, 3H), 3.81 (s, 3H); LCMS: ret. time: 22.53 min.; purity: 100%; MS (m/e): 341 (MH+).
