Reaction Steps

4-Amino-3-nitrophenol (1.09 g, 7.072 mmol) was dissolved into ethanol (50 ml). Palladium on charcoal (10%, 220 mg) was added and the mixture was stirred for 3.5 h under hydrogen atmosphere. The reaction mixture was filtered over Celite® and concentrated to afford 138a (930 mg, 100% yield) as a dark brown solid.
