실험 절차

A solution of NH4Cl (45 mg, 0.85 mmol) in water (10 mL) was added in one portion to a stirred mixture of N-(5-chloro-4-pyrazolo[1,5-a]pyridin-3-ylpyrimidin-2-yl)-N′-(2-dimethylaminoethyl)-2-methoxy-N′-methyl-5-nitrobenzene-1,4-diamine (Intermediate 34, 600 mg, 1.21 mmol) and iron (405 mg, 7.24 mmol) in ethanol (30 mL). The resulting mixture was stirred at 105° C. for 3 h. The mixture was then concentrated in vacuo and the resulting residue was mixed with DMF (10 mL) and purified by ion exchange chromatography, using an SCX column. The desired product was eluted from the column using 0.35M methanolic ammonia in CH2Cl2 and pure fractions were concentrated in vacuo to give the title compound (530 mg, 94%) as a brown gum; 1H NMR: 2.16 (6H, d), 2.38 (2H, t), 2.66 (3H, d), 2.92 (2H, t), 3.66 (3H, s), 4.60 (2H, s), 6.78 (1H, s), 6.92 (1H, s), 7.12 (1H, t), 7.27-7.4 (1H, m), 8.38 (1H, s), 8.43 (1H, d), 8.49 (1H, s), 8.83 (1H, d), 8.95 (1H, s); m/z: ES+ MH+ 467.
