Procedure
2,4,5-Trichloropyrimidine (978 mg, 5.33 mmol) was dissolved in Tetrahydrofuran (30 mL), then Potassium carbonate (1.52 g, 11.0 mmol) was added. 2-Methoxy-4-morpholin-4-yl-phenylamine (1.030 g, 4.95 mmol) was added, and the reaction was stirred under an atmosphere of Nitrogen, overnight. The reaction was partitioned between 30 mL water, 30 mL dichloromethane and separated. The aq. layer was extracted once with 30 mL dichloromethane, the combined organics washed once with 50 mL brine, then dried over sodium sulfate. The contents were concentrated onto silica gel, and chromatographed on an ISCO cartridge (120 g SiO2, 0-40% EA:Hex). (2,5-Dichloro-pyrimidin-4-yl)-(2-methoxy-4-morpholin-4-yl-phenyl)-amine was isolated as a yellow solid (1.40 g, 80%). m.p.=156-160° C.; LCMS (m/e)=355 (M+1); 1H-NMR (CDCl3, 400 MHz) δ 8.30 (d, 1H, J=8.8 Hz), 8.13 (s, 1H), 7.87 (s, 1H), 6.57 (d, 1H, J=8.8 Hz), 6.52 (s, 1H), 3.93 (s, 3H), 3.88 (t, 4H, J=4.8 Hz), 3.16 (t, 4H, J=4.8 Hz).
