Bromine → Methyl 4-amino-3-bromo-5-methoxybenzoate

Participants

Reaction Steps

10.5 Grams (55 mmole) of methyl 3-methoxy-4-aminobenzoate was dissolved in 80 ml methanol, and 3.0 ml bromine (55 mmole) in 20 ml acetic acid was added dropwise at room temperature. The solution was stirred for three hours at room temperature and the solvents were evaporated under reduced pressure. The residue was treated with sodium bicarbonate solution and the product was filtered and air-dried to yield 16.5 grams of methyl 3-bromo-5-methoxy-4-aminobenzoate.
