Versuchsvorschrift

A mixture of (N-{4-[(3R)-3-dimethylaminopyrrolidin-1-yl]-2-methoxy-5-nitrophenyl}-4-(1-methylindol-3-yl)pyrimidin-2-amine (Intermediate 104, 360 mg, 0.74 mmol), iron (247 mg, 4.43 mmol) and NH4Cl (27.6 mg, 0.52 mmol) in ethanol (12 mL) and water (4 mL) was heated at reflux for 2 h. The crude mixture was purified by ion exchange chromatography, using an SCX column. The desired product was eluted from the column using 7M methanolic ammonia and appropriate fractions were combined and concentrated in vacuo onto silica. Purification by FCC, eluting with 0-5% 7N methanolic ammonia in CH2Cl2 gave the title compound (280 mg, 83%) as a beige foam; 1H NMR: 1.69-1.83 (1H, m), 1.97-2.10 (1H, m), 2.18 (6H, s), 2.78-2.87 (1H, m), 2.88-2.98 (2H, m), 3.11 (1H, dd), 3.15-3.22 (1H, m), 3.74 (3H, s), 3.87 (3H, s), 4.29 (2H, br s), 6.70 (1H, s), 7.1-7.19 (2H, m), 7.21-7.28 (1H, m), 7.46 (1H, s), 7.51 (1H, d), 7.78 (1H, s), 8.25 (1H, d), 8.29 (1H, s), 8.43 (1H, d); m/z: ES+ MH+ 458.35.
