実験手順

Water (4 mL) was added in one portion to a mixture of N′-(2-dimethylaminoethyl)-N-[4-(1H-indol-3-yl)pyrimidin-2-yl]-2-methoxy-N′-methyl-5-nitrobenzene-1,4-diamine (Intermediate 169, 270 mg, 0.59 mmol), iron (196 mg, 3.51 mmol), NH4Cl (21.9 mg, 0.41 mmol) and ethanol (24 mL). The resulting mixture was heated at 105° C. for 3 h then filtered through diatomaceous earth (Celite™). The filtrate was concentrated in vacuo and then part-purified by ion exchange chromatography, using an SCX column and eluting with 0.35M methanolic ammonia. Appropriate fractions were combined and concentrated in vacuo to give the title compound (244 mg, 97%) as a brown solid which was used without further purification; 1H NMR: 2.18 (6H, s), 2.37 (2H, s), 2.64 (3H, s), 2.90 (2H, s), 3.76 (3H, s), 6.77 (1H, s), 7.03-7.26 (3H, m), 7.46 (1H, d), 7.52 (1H, s), 7.74 (1H, s), 8.18-8.35 (2H, m), 8.42 (1H, d), 11.72 (1H, s); m/z: ES+ MH+ 432.
