3-BROMO-2,5-DIAMINOPYRIDINE, 99% Use and Manufacturing
General procedure: Into a 30-mL flask, compound 2a-c was suspended in MeOH(6.0 mL). A solution of NH4Cl (5.0 equivalent.) in H2O (6.0 mL)was added followed by Fe powder (5.0 equivalents.). The suspensionwas stirred at 80 C for 2 h. which was filtered off at about50 C. The filtrate was concentrated and purified by column chromatography(KANTO 60 N, CH2Cl2/MeOH = 97/3 to 92/8) to give ared solid compound.
