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

Participants

Reaction Steps

A mixture of 1-(aminomethyl)-4-propylpyrrolidin-2-one x76 (1 eq, 17.09 mmol, 2.67 g), 2-chloro-3-nitropyridine (1 eq, 17.09 mmol, 2.709 g) and triethylamine (1.1 eq, 18.8 mmol, 1.902 g, 2.62 ml) in dioxane (20 ml) is refluxed 48 h. After cooling, the crude mixture is filtrated and the dioxane is distilled under vacuum. The residue is purified by preparative chromatography to afford 2.5 g of 1-{[(3-nitropyridin-2-yl)amino]methyl}-4-propylpyrrolidin-2-one x77.
