反应详情

A parr bottle was charged with palladium on activated carbon (5%, 0.204 g). A solution of 3-hydroxy-4-nitrobenzonitrile (1.36 g, 0.00829 mol) in 41 ml of ethanol was added. The reaction mixture was placed under 25 psi of hydrogen gas and shaken for 1 hour. TLC (1:1 hexane:ethyl acetate) shows that no starting material remained. The mixture was filtered through Celite® and evaporated to yield 3-hydroxy-4-aminobenzonitrile, 1.08 g (0.00806 mol, 97%).
