Abstract: 2,3-dimethoxy-5-hydroxymethyl-6-methyl-1,4-benzoquinone (V) was prepared with a 75 % yield by means of a reaction sequence starting from 2,3,4,5-tetramethoxytoluene via Blanc chloromethylation reaction, Kornblum oxidation, NaBH4 reduction and ceric ammonium nitrate oxidation. The procedure is operationally simple and amenable to gram-scale synthesis.

Keywords: coenzyme Q – idebenone – Kornblum oxidation – ceric ammonium nitrate oxidation
