4-Fluoroaniline → 5-fluoro-N,N'-bis(4-fluorophenyl)pyrimidine-2,4-diamine

Participants

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-fluoroaniline were reacted to yield N2,N4-bis(4-fluorophenyl)-5-fluoro-2,4-pyrimidinediamine. 1H NMR (CDCl3): δ 8.79 (d, 2H, J=5.4 Hz), 7.40 (m, 2H), 7.30 (m, 2H), 6.90 (m, 4H); 19NMR (CDCl3): −32425 (s, 1F), −32940 (s, 1F), −45525 (s, 1F); LCMS: ret. time: 23.53 min.; purity: 100%; MS (m/e): 317 (MH+).
