A parr bottle was charged with palladium on activated carbon (5%, 0.196g). A solution of 2-nitro-3-hydroxybenzonitrile (1.31 g, 0.008 mol) in 40 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 2-amino-3-hydroxybenzonitrile, 1.01 g (0.0075 mol, 94%).
