1-{[(3-Nitropyridin-2-yl)amino]methyl}-4-propylpyrrolidin-2-one → 1-{[(3-Aminopyridin-2-yl)amino]methyl}-4-propylpyrrolidin-2-one

Participants

Reaction Steps

Palladium on charcoal (10% wt, 0.478 g) is added to a solution of 1-{[(3-nitropyridin-2-yl)amino]methyl}-4-propylpyrrolidin-2-one x77 (1 eq, 2.5 g, 8.983 mmol) and NH4CO2H (5 eq, 44.9 mmol, 2.832 g) in water and methanol (1/1 (v/v), 35 ml). The resulting slurry is kept under agitation during 16 hours at room temperature, then filtration over celite and evaporation of the crude mixture afford 2.524 g of 1-{[(3-aminopyridin-2-yl)amino]methyl}-4-propylpyrrolidin-2-one x78.
