実験手順

To a solution of 2-aminobenzene-1,4-diol hydrochloride (3.58 g) in pyridine (40 mL) was added potassium ethylxanthate (3.91 g), and the mixture was stirred with heating under reflux for 3 hr. After allowing to cool to room temperature, the reaction solution was concentrated under reduced pressure, and the obtained residue was dissolved in water, and the solution was acidified with 1M hydrochloric acid. The precipitated solid was collected, and washed with water to give the title compound (2.08 g).
