An economic four-step synthesis of 2,6-dimethoxy-1,4-benzoquinone was achieved in 68% overall yield starting from aniline. The reaction sequence involved conversion to 1,3,5-tribromoaniline, deamination, methoxylation, and oxidation. The procedure is operationally simple and amenable to scale-up production.
