Versuchsvorschrift

A mixture of N-[4-[(3S)-3-dimethylaminopyrrolidin-1-yl]-2-methoxy-5-nitrophenyl]-4-(1-methylindol-3-yl)pyrimidin-2-amine (Intermediate 149, 230 mg, 0.47 mmol), iron (158 mg, 2.83 mmol), NH4Cl (17.7 mg, 0.33 mmol), ethanol (9 mL) and water (3 mL) was heated at reflux for 50 minutes. The reaction was judged to be incomplete so further iron (158 mg, 2.83 mmol) and NH4Cl (17.7 mg, 0.33 mmol) was added and the mixture was heated at reflux for a further 0.5 h. After cooling, the mixture was filtered and concentrated in vacuo. Purification by FCC, eluting with 1.5-7% 7M methanolic ammonia in CH2Cl2 gave the title compound (187 mg, 87%) as a grey foam; 1H NMR: 1.78 (1H, m), 2.06 (1H, m), 2.20 (6H, s), 2.86 (1H, d), 2.90-3.01 (2H, m), 3.12 (1H, m), 3.15-3.23 (1H, m), 3.76 (3H, s), 3.88 (3H, s), 4.27 (2H, s), 6.72 (1H, s), 7.14 (1H, d), 7.15-7.21 (1H, m), 7.22-7.34 (1H, m), 7.50 (1H, s), 7.52 (1H, d), 7.74 (1H, s), 8.26 (1H, s), 8.28 (1H, s), 8.43 (1H, d); m/z: ES+ MH+ 458.75.
