실험 절차

A solution of NH4Cl (0.021 g, 0.38 mmol) in water (3 mL) was added in one portion to a stirred suspension of 4-(1H-indol-3-yl)-N-[2-methoxy-4-(4-methylpiperazin-1-yl)-5-nitrophenyl]pyrimidin-2-amine (Intermediate 67, 0.235 g, 0.51 mmol) and iron (0.171 g, 3.07 mmol) in ethanol (9 mL) and the mixture was stirred at 105° C. for 18 h. The mixture was then concentrated in vacuo and the resulting residue was dissolved in DMF (20 mL). Purification by ion exchange chromatography, using an SCX column, eluting with 0.35M methanolic ammonia in CH2Cl2 and concentration of the appropriate fractions gave the title compound (0.206 g, 94%) as a yellow solid; m/z: ES+ MH+ 430.51.
