실험 절차

A mixture of 5-chloro-N-[4-(3-dimethylaminoazetidin-1-yl)-2-methoxy-5-nitrophenyl]-4-pyrazolo[1,5-a]pyridin-3-ylpyrimidin-2-amine (Intermediate 25, 265 mg, 0.54 mmol), iron (179 mg, 3.21 mmol) and NH4Cl (20.05 mg, 0.37 mmol) was heated at reflux in ethanol (6 mL) and water (2 mL) for 1 h. The crude product 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 concentrated in vacuo to give the title compound (235 mg, 94%) as a yellow solid which was used without further purification; 1H NMR: 2.13 (6H, s), 3.07 (1H, s), 3.50 (2H, t), 3.66 (3H, s), 4.00 (3H, t), 4.05 (2H, s), 6.28 (1H, s), 6.79 (1H, s), 7.10 (1H, t), 7.3-7.39 (1H, m), 8.33 (1H, s), 8.37 (1H, s), 8.80 (1H, d), 8.93 (1H, s); m/z: ES+ MH+ 465.25.
