Procedure

The reaction of 4,6-dichloropyrimidine with excess 3-hydroxyaniline in MeOH at 800° C. for 24 h followed by dilution with water and acidification gave the crude product which was purified by silica gel column chromatography to obtain 6-chloro N4-(3-hydroxyphenyl)-4-pyrimidineamine. 1H NMR (CD3OD): δ 8.36 (d, 1H, J=1.2 Hz), 7.15 (t, 1H, J=8.4 Hz), 6.93 (dd, 1.2 and 8.1 Hz), 6.74 (d, 1H, J=1.2 Hz), 6.55 (dd, 1.8 and 8.1 Hz); LCMS (m/e): ret. time: 19.75 min.; purity: 99%; MS (m/e): 222 (MH+).
