Reaction Steps

1-(2-chloro-5-nitro-4-pyridyl)-4-methyl-piperazine (580 mg, 2.260 mmol) was dissolved in AcOH (20 mL)/Water (2 mL) and Fe (2.524 g, 45.20 mmol) was added. The resulting mixture was stirred at 50° C. for 30 minutes. The reaction was cooled to ambient temperature then loaded onto 50 g SCX-2 cartridge (pre-washed with MeOH). The cartridge was washed with DCM/MeOH mixtures, before the product was eluted with 2M NH3 in MeOH/DCM mixtures. The solvent was removed in vacuo to give 6-chloro-4-(4-methylpiperazin-1-yl)pyridin-3-amine as a purple solid (510 mg, 99% Yield). MS (ES+) 227.1.
