1-[(3-Nitroquinolin-4-ylamino)methyl]cyclohexanol → 1-[(3-Aminoquinolin-4-ylamino)methyl]cyclohexanol

Participants

Reaction Steps

A suspension of 1-{[(3-nitroquinolin-4-yl)amino]methyl}cyclohexanol (15.0 g, 49.8 mmol) in ethyl acetate (225 mL) in a Parr vessel was purged with nitrogen; 5% platinum on carbon (1.5 g) was added. The reaction was placed under hydrogen pressure (35 psi, 2.4×105 Pa) for 3.5 hours and then filtered through a layer of CELITE filter agent. The filter cake was washed with ethyl acetate (100 mL), and the filtrate was concentrated under reduced pressure to provide 1-{[(3-aminoquinolin-4-yl)amino]methyl}cyclohexanol as a yellow solid.
