Versuchsvorschrift
A solution of 2-(2-methoxy-ethoxy)-phenylamine (800 mg) in DMSO (15 mL) was treated with 2,4,5-trichloropyrimidine (1.1 g) and DIEA (1.8 mL) for 16 hours. The mixture was diluted with DCM (50 mL) and washed with brine three times. The organic layer was dried over sodium sulfate and concentrated. Silica gel chromatography provided 1.0 g of (2,5-dichloro-pyrimidin-4-yl)-[2-(2-methoxy-ethoxy)-phenyl]-amine: 1H NMR (300 MHz, CDCl3) δ8.48 (d, 1H), 8.28 (bs, 1H), 8.19 (s, 1H), 7.06 (m, 2H), 6.95 (d, 1H), 4.20 (t, 2H), 3.75 (t, 2H), 3.42 (s, 3H); MS (m/e) 314 (M+1).
