Versuchsvorschrift

A mixture of N-[5-chloro-4-(1-methylindol-3-yl)pyrimidin-2-yl]-N′-(2-dimethylamino-ethyl)-2-methoxy-N′-methyl-5-nitrobenzene-1,4-diamine (Intermediate 98, 553 mg, 1.08 mmol), iron (363 mg, 6.51 mmol) and NH4Cl (43.5 mg, 0.81 mmol) in ethanol (23 mL) and water (7.67 mL) were heated at reflux for 1.5 h. The mixture was then cooled and concentrated in vacuo. The resulting residue was dissolved in CH2Cl2 (100 mL) and CH3OH (10 mL) and this mixture was stirred for 0.25 h and then filtered. The filter cake was washed with further CH2Cl2 and CH3OH and the combined organics were dried (MgSO4) and concentrated in vacuo. Purification by FCC, eluting with 0-5% methanolic ammonia in CH2Cl2 provided a solid. This solid was dissolved in diethyl ether and a small amount of brown precipitate was removed by filtration. The filtrate was concentrated in vacuo to give the title compound (409 mg, 79%) as a brown glass; 1H NMR: (CDCl3) 2.26 (6H, s), 2.38-2.43 (2H, m), 2.68 (3H, s), 2.94-2.98 (2H, m), 3.84 (3H, s), 3.91 (3H, s), 6.71 (1H, s), 7.26-7.36 (2H, m), 7.40 (1H, d), 7.63 (1H, s), 8.09 (1H, s), 8.21 (1H, s), 8.33 (1H, s), 8.67 (1H, d); m/z: ES+ MH+ 480.32.
