Reaction Conditions

Reaction Steps

In a 250 ml single neck round bottom flask was added 2,3-diaminophenol (10 g, 80.55 mmol) to ethanol (100 ml). This mixture was heated to 50° C. to achieve dissolution. The resulting solution is cooled to −5 to 0° C. and an excess of anhydrous hydrogen chloride gas was added to form a viscous slurry. The resulting mixture was stirred for two hours at ˜0° C., then filtered, and rinsed with chilled methanol (30 ml). The solvents were removed in vacuo and the residue was dried overnight.
