Versuchsvorschrift

A solution of N2,N4-bis(3-methoxycarbonylphenyl)-5-fluoro-2,4-pyrimidinediamine (100 mg, 0.25 mmol) and NaOH (140 mg, 3.5 mmol) in THF:H2O (5 mL, each) was stirred at room temperature overnight. The reaction mixture was diluted with water (60 mL) and ethyl acetate (60 mL). The aqueous layer was separated, acidified with 1N HCl solution to pH 3. The formed precipitate was collected by filtration and recrystallized from methanol to give N2,N4-bis(3-carboxyphenyl)-5-fluoro-2,4-pyrimidinediamine (54 mg, 58%) as a white solid. 1H NMR (CD3OD): δ 7.31 (t, J=8.1 Hz, 1H), 7.42 (t, J=8.1 Hz, 1H), 7.61 (dm, J=7.8 Hz, 1H), 7.76 (dm, J=8.4 Hz, 1H), 7.89 (dm, J=7.2 Hz, 1H), 7.98 (d, J=3.6 Hz, 1H), 8.01 (m, 1H), 8.20 (m, 1H), 8.37 (m, 1H); LCMS: ret. time: 15.77 min.; purity: 98.84%; MS (m/e): 369.03 (MH+).
