Reaction Steps

A suspension of N-(N',N'-dimethylamino)-1-methyl-4-nitroimidazole-2-carboxamide (2.01 g, 9.4 mmol) and 5% Pd on charcoal (0.8 g) in chilled methanol (100 mL) was purged of air and hydrogenated at room temperature and atmospheric pressure for 4 hours. The catalyst was removed by filtration and the solvent was evaporated under reduced pressure to give N-(N',N'-dimethylamino)-1-methyl-4-aminoimidazole-2-carboxamide as a glassy solid which is unstable and used directly in the next step.
