Versuchsvorschrift

2,4,5-Trichloropyrimidine (0.960 g, 5.2 mmol) was dissolved in tetrahydrofuran (20 mL). Potassium carbonate (1.20 g, 8.70 mmol) was added, followed by 3-morpholinoaniline (0.875 g, 4.90 mmol). After stirring overnight, water (30 mL) and dichloromethane (30 mL) were added, the phases separated and the aqueous layer extracted once with dichloromethane (30 mL). The combined organic fractions were dried over sodium sulfate, concentrated onto silica gel and chromatographed (120 g SiO2, 0-50% EA:Hex). (2,5-Dichloro-pyrimidin-4-yl)-(3-morpholin-4-yl-phenyl)-amine was isolated as an off-white solid (1.16 g, 73%). m.p.=142-145° C.; LCMS (m/e) 325 (M+1); 1H-NMR (CDCl3, 400 MHz) δ 8.20 (s, 1H), 7.38 (s, 1H), 7.28 (m, 1H), 7.21 (s, 1H), 7.01 (d, 1H, J=7.8 Hz), 6.75 (d, 1H, J=8.4 Hz), 3.88 (t, 4H, J=4.8 Hz), 3.21 (t, 4H, J=4.8 Hz).
