実験手順
tert-Butyl N-[2-[[5-methoxy-4-[[4-(1-methylindol-3-yl)pyrimidin-2-yl]amino]-2-nitrophenyl]-methylamino]ethyl]-N-methylcarbamate (Intermediate 172, 428 mg, 0.76 mmol), iron (255 mg, 4.57 mmol) and NH4Cl (30.6 mg, 0.57 mmol) were heated in ethanol (16 mL) and water (5.33 mL) at reflux for 1.5 h (heating block at 100° C.) and then the mixture was cooled and concentrated in vacuo. The resulting residue was triturated in 10% CH3OH/CH2Cl2 (30 mL) and filtered. The residues were triturated again with 10% CH3OH/CH2Cl2 (30 mL) and filtered. The combined filtrates were washed with brine, dried (MgSO4) and concentrated in vacuo. Purification by FCC, eluting with 0-5% CH3OH in CH2Cl2 gave the title compound (380 mg, 94%) as a light brown foam; 1H NMR: 1.41 (9H, s), 2.64 (3H, s), 2.80 (3H, s), 2.95 (2H, t), 3.34 (2H, t), 3.77 (3H, s), 3.89 (3H, s), 4.40 (2H, s), 6.78 (1H, s), 7.14-7.20 (2H, m), 7.23-7.27 (1H, m), 7.52 (1H, d), 7.55 (1H, s), 7.75 (1H, s), 8.28 (1H, d), 8.29 (1H, s), 8.42 (1H, d); m/z: ES+ MH+ 532.37.
