Reaction Steps
A solution of 2,3-dimethoxy-5-methyl-6-(3'-carboxypropyl)-1,4-benzoquinone (formula I-2 wherein R=H3CO, n=2 in the free form) (0.8 part) in ethanol (3 volume parts) saturated with dry hydrogen chloride was stirred at room temperature for 1 hour. The residue upon removal of the solvent was subjected to chromatography on silica gel and eluted with chloroform to give 2,3-dimethoxy-5-methyl-6-(3'-ethoxycarbonylpropyl)-1,4-benzoquinone (formula I-2 wherein R=H3CO, n=2, in the form of ethyl ester) (0.88 part) as an orange oil.
