Reaction Steps

A mixture of 4-(1H-indol-3-yl)-N-[2-methoxy-4-(4-methylpiperazin-1-yl)-5-nitrophenyl]-5-methylpyrimidin-2-amine (Intermediate 13, 157 mg, 0.33 mmol), iron (111 mg, 1.99 mmol) and NH4Cl (12.41 mg, 0.23 mmol) was heated in ethanol (6 mL) and water (2 mL) at reflux for 2 h. The mixture was then cooled and concentrated in vacuo to give a thick slurry. CH2Cl2 (100 mL) and CH3OH (10 mL) were then added and the mixture was stirred for 0.25 h, then filtered. The filter cake was washed with CH2Cl2 (50 mL) and CH3OH (5 mL) and the combined organic solutions were dried (MgSO4) and concentrated in vacuo. Purification by FCC, eluting with 1-5% methanolic ammonia in CH2Cl2 gave the title compound (113 mg, 77%) as a pale yellow dry film; m/z: ES+ MH+ 444.53.
