Methanol → Methyl 2-hydroxy-3-phenylbenzoate

関与物質

反応手順

Methanol (50 ml) was treated with concentrated sulphuric acid (4.9 g, 2.66 ml) cautiously. 2-Hydroxy-3-phenylbenzoic acid (10.7 g, 50 mmol) was added and the reaction mixture stirred at ambient temperature for 18 hours. The mixture was then heated at reflux for 4 hours, cooled to ambient temperature and evaporated. The residue was partitioned between ethyl acetate/and water, the organic layer washed twice with water, dried (MgSO4) and evaporated to give methyl 2-hydroxy-3-phenylbenzoate.
