Reaction Steps

A solution of 2,3,5-trimethyl-6-(2'-ethoxycarbonylethyl)-1,4-benzoquinone (formula I-2 wherein R=H3C, n=1, in the form of ethyl ester) (0.39 part) in diethyl ether (50 volume parts) was treated with lithium aluminum hydride in the same manner as Example 53 to give 2,3,5-trimethyl-6-(3'-hydroxypropyl)-hydroquinone (formula III-2 wherein R=H3C, X=Y=OH, n=1 in the free form). The product was treated with ferric chloride in the same manner as Example 53 and then subjected to column chromatography on silica gel and eluted with chloroform. The procedure provided 2,3,5-trimethyl-6-(3'-hyydroxypropyl)-1,4-benzoquinone (formula IV-2 wherein R=H3C, n=1, in the free form) (0.25 part) as a yellow oil.
