The title compound was readily prepared from 2, 3, 4, 5-tetramethoxytoluene via the Blanc reaction, oxidation, and alkylation. The described method provides a good yield of the heterocyclic substitute at the C-5 position of the Coenzyme Q homologue and is suitable for the synthesis of other homologues.

A series of 2,3-dimethoxy-5-methyl-1,4-benzoquinones (Coenzyme Q) substituted at the C-6 position with various groups were designed and synthesized based on the Coenzyme Q10 as potent antioxidant. In vitro antioxidant activities of these compounds were evaluated and compared with commercial antioxidant Coenzyme Q10 employing DPPH assay. All these synthesized Coenzyme Q analogues are found to exhibit good antioxidant activities. Of which Compound 8b bearing a N-benzoylpiperazine group at the C-6 position showed more potent inhibition of DPPH radical than Coenzyme Q10. All these results suggested the applicability of the Coenzyme Q analogues as potent antioxidants for combating oxidative stress.
Alternative synthesis of 5-chloromethyl-2,3-dimethoxy-6-methyl-1, 4-benzoquinone: A key intermediate for preparing coenzyme Q analogues
Wang, Jin,Yang, Jian,Yang, Bo,Sun, Jia-Qiang,Yang, Tao
, p. 724 - 725 (2011/04/24)
The title compound, a key intermediate for preparing Coenzyme Qn family, was prepared in high yield by a reaction sequence starting from the commercially available 3, 4, 5-trimethoxy-benzadehyde via Wolff-Kishner reduction, Vilsmeier-Haack reaction, Blanc chloromethylation reaction, Dakin reaction and oxidation.
