Water → Methyl 5-bromo-4-ethyl-2-hydroxybenzoate

Participants

Reaction Steps

To a solution of methyl 4-ethyl-2-hydroxybenzoate (1.43 g) in acetic acid (15.0 mL) was added bromine (1.40 g) under ice-cooling, and the mixture was stirred at room temperature for 2 hr under argon atmosphere. To the reaction mixture was added water, the resulting solid was collected by filtration, and dried under reduced pressure to give the title compound (2.21 g) as a mixture with methyl 3,5-dibromo-4-ethyl-2-hydroxybenzoate (2:1). This compound was used in the next step without an additional purification.
