Ethyl 3-[(3-nitroquinolin-4-yl)amino]butanoate → Ethyl 3-[(3-aminoquinolin-4-yl)amino]butanoate

Participants

Reaction Steps

A Parr vessel was charged with a solution of ethyl 3-[(3-nitroquinolin-4-yl)amino]butanoate (11.5 g, 37.9 mmol) in acetonitrile (150 mL) followed by 5% platinum on carbon (1.2 g). The mixture was placed under hydrogen pressure overnight and then filtered through a layer of CELITE filter agent. The filtrate was concentrated under reduced pressure and further dried under high vacuum to provide 10.5 g of ethyl 3-[(3-aminoquinolin-4-yl)amino]butanoate as a sticky, yellow solid.
