A process for the preparation of 2-methoxy-3,6-dichloro-benzoic acid comprising the steps of catalytically debrominating 2-hydroxy-5-bromo-3,6-dichloro-benzyl alcohol to produce 2-hydroxy-3,6-dichloro-benzyl alcohol, methylating said 2-hydroxy-3,6 -dichloro-benzyl alcohol at the 2-hydroxy group to produce 2-methoxy-3,6-dichloro-benzyl alcohol, oxidizing said 2-methoxy-3,6-dichloro-benzyl alcohol to produce 2-methoxy-3,6-dichloro-benzoic acid, and recovering said 2-methoxy-3,6-dichloro-benzoic acid.
