実験手順

Water (4 mL) was added to a stirred mixture of N-{4-[(3R)-3-dimethylaminopyrrolidin-1-yl]-2-methoxy-5-nitrophenyl}-4-(1H-indol-3-yl)pyrimidin-2-amine (Intermediate 165, 286 mg, 0.60 mmol), iron (202 mg, 3.62 mmol), NH4Cl (22.6 mg, 0.42 mmol) and ethanol (24 mL). The resulting mixture was stirred at 105° C. for 3 h and was then filtered through diatomaceous earth (Celite™) and concentrated in vacuo. Part-purification by ion exchange chromatography, using an SCX column and eluting with 0.35M methanolic ammonia gave the title compound (312 mg, 116%) as a brown gum, which was used without further purification; 1H NMR: 2.13 (2H, d), 2.32 (2H, d), 2.80 (6H, d), 2.87-2.98 (2H, m), 3.19 (2H, d), 3.77 (3H, s), 6.74 (1H, s), 7.17 (4H, ddd), 7.46 (1H, d), 7.56 (1H, s), 7.77 (1H, s), 8.28 (2H, dd), 8.43 (1H, d), 11.76 (1H, s); m/z: ES+ MH+ 444.
