Reaction Steps

A solution of 3-hydroxy-4-nitrobenzaldehyde O-methyloxime (5.9 g, 30 mmol) in ethanol (100 mL) and tetrahydrofuran (100 mL) is degassed with solid carbon dioxide, then charged with 10% palladium on carbon (500 mg) and concentrated hydrochloric acid (5.5 mL). The mixture is shaken under 50 psi hydrogen gas until consumption of hydrogen had ceased. The mixture is then filtered through a pad of diatomaceous earth, and the filtrate is concentrated under reduced pressure to give 2-amino-5-(aminomethyl)phenol dihydrochloride (6.1 g, 97%).
