Reaction Steps
Bromine was added to an acetic acid solution of methyl 3-ethoxythiophene-2-carboxylate, followed by stirring at room temperature. The product was separated by silica gel column chromatography to obtain methyl 5-bromo-3-ethoxythiophene-2-carboxylate (F: 265, 267) and methyl 4-bromo-3-ethoxythiophene-2-carboxylate (F: 265, 267).
