反応手順

In a manner similar to the preparation of N2,N4-bis(3-hydroxyphenyl)-5-fluoro-2,4-pyrimidinediamine, 2,4-dichloro-5-fluoropyrimidine and 4-ethylaniline were reacted to yield N2,N4-bis(4-ethylphenyl)-5-fluoro-2,4-pyrimidinediamine. 1H NMR (CDCl3): δ 8.83 (bs, 1H), 7.77 (d, 1H, J=3.9 Hz), 7.48 (d, 2H, J=8.7 Hz), 7.40 (d, 2H, J=8.7 Hz), 7.31 (bs, 1H), 7.18 (d, 2H, J=8.7 Hz), 7.11 (d, 2H, J=8.7 Hz), 2.68-2.61 (m, 4H), 1.28-1.21 (m, 6H); LCMS: ret. time: 29.17 min.; purity: 100%; MS (m/e): 337 (MH+).
