実験手順

A mixture of 5-chloro-N-[4-(3-dimethylaminoazetidin-1-yl)-2-methoxy-5-nitrophenyl]-4-(1-methylindol-3-yl)pyrimidin-2-amine (Intermediate 113, 285 mg, 0.56 mmol), iron (188 mg, 3.37 mmol) and NH4Cl (22.51 mg, 0.42 mmol) in ethanol (9 mL) and water (3 mL) was heated at reflux for 2 h. The mixture was then cooled and filtered through diatomaceous earth (Celite™). The filtrate was concentrated in vacuo and the resulting residue was dissolved in CH2Cl2. This solution was washed with brine, dried (MgSO4) and concentrated in vacuo. Purification by FCC, eluting with 1-20% 7N methanolic ammonia in CH2Cl2 gave the title compound (263 mg, 98%) as a brown dry film; 1H NMR: (CDCl3) 2.21 (6H, s), 3.08-3.18 (1H, m), 3.30 (2H, br s), 3.58 (2H, t), 3.86 (3H, s), 3.88 (3H, s), 3.93 (2H, t), 6.38 (1H, s), 7.2-7.42 (3H, m, partially obscured by chloroform signal), 7.50 (1H, s), 7.99 (1H, s), 8.20 (1H, s), 8.31 (1H, s), 8.63 (1H, d); m/z: ES+ MH+ 478.
