Reaction Steps
A solution of 0.542 gm. (0.002 mole) of 3-nitro-6-(2-pyridylthio) imidazo [1,2-a] pyridine in 20 ml. of dioxane is reduced at 40 psi. under a hydrogen atmosphere with 0.500 g. of 5% palladium on carbon as catalyst. When the uptake of hydrogen is complete, the catalyst is removed by filtration. The filtrate is evaporated in vacuo to yield 3-amino-6-(2-pyridylthio) imidazo [1,2-a] pyridine.
