Triethylamine → (2-Nitrophenyl){(2-oxo-4-propyl-pyrrolidin-1-yl)methyl}amine

Participants

Reaction Steps

A mixture of 1-aminomethyl-4-propyl-pyrrolidin-2-one a27 (1 eq, 17.09 mmol, 2.67 g), 2-fluoro-nitrobenzene (1 eq, 17.09 mmol, 2.411 g, 1.802 ml) and triethylamine (1.1 eq, 18.8 mmol, 1.902 g, 2.62 ml) in dioxane (20 ml) was refluxed 48 h. After cooling, the crude mixture was filtrated and the dioxane was distilled under vacuum. The residue was purified by preparative chromatography on reverse phase to give (2-nitrophenyl){(2-oxo-4-propyl-pyrrolidin-1-yl)methyl}amine a28 (2.747 g, 58%). LC/MS (MH+): 278.
