Ethanol → 4-[(3-Aminoquinolin-4-yl)amino]butan-1-ol

Participants

Reaction Steps

Catalyst (5% Pd/C) was added to a suspension of 4-[(3-nitroquinolin-4-yl)amino]butan-1-ol (18.2 g, 69.6 mmol) in toluene (450 mL) in a Parr vessel. The vessel was placed on a shaker and pressurized with hydrogen. The next day ethanol (60 mL) and additional catalyst were added and the vessel was again pressurized with hydrogen. After 1 hour analysis by TLC indicated that all of the starting material had been consumed. The reaction mixture was filtered through a layer of CELITE filter aid and then concentrated under reduced pressure to provide 17 g of 4-[(3-aminoquinolin-4-yl)amino]butan-1-ol.
