ChEBI: 2-anthrol is an anthrol. | [Synthesis]
General procedure for the synthesis of 2-hydroxyanthraquinone from 2-hydroxyanthracene: NaBH4 (3.8 g, 100 mmol) was dissolved in a 1 M Na2CO3 (150 mL) solution in a large 2 L beaker, isopropanol (25 mL) was added and the resulting solution was heated to boiling point. Subsequently, a 1M Na2CO3 (50 mL) solution of 2-hydroxyanthraquinone (2.5 g, 10 mmol) was added in batches under vigorous stirring and the foam was broken with a glass rod. The reaction mixture was heated at boiling point for 20 min, cooled to room temperature and acidified with 3M HCl. The product was filtered, washed thoroughly with water and finally dried with KOH in a vacuum desiccator for 2 days to give 2-hydroxyanthracene in yellow solid form (2 g, 93% yield). The product was pure enough to be used in the next step of the reaction without further purification. | [References]
