実験手順
9-(2',3',4'-Trimethoxy-6'-methylbenzoyl)nonanoic acid (formula II-1 wherein R=Y=H3CO, X=H, n=8, in the free form) (0.09 part) was reduced with zinc amalgam (0.2 part) by a procedure similar to that described in Example 10 and oxidized with 30% hydrogen peroxide (10 volume parts) in acetic acid. Following the addition of water, the reaction mixture was extracted with diethyl ether (500 volume parts) and the extract was washed with water and dried. The ether was then removed by distillation. The procedure provided 2,3-dimethoxy-5-methyl-6-(9'-carboxynonyl)-1,4-benzoquinone (formula I-2 wherein R=H3CO, n=8, in the free form).
