Hydrogen chloride was bubbled into a gently boiling solution of the known 3-(2-hydroxybenzoyl)propionic acid (10 g, 0.05 mole) in dry methanol (20 ml) until esterification was complete. The solution was poured into ice-water and the ester extracted into dichloromethane. The organic solution was washed with water and evaporated to give methyl 3-(2-hydroxybenzoyl)-propionate (10.55 g. 98%) as a pale yellow oil.
