実験手順

A solution of 2,3,5-trimethyl-6-(5'-ethoxycarbonylpentyl)-1,4-benzoquinone (formula I-2 wherein R=H3C, n=4, in the form of ethylester) (0.1 part) in diethyl ether (10 volume parts) was treated with lithium aluminum hydride in the same manner as Example 53 to give 2,3,5-trimethyl-6-(6'-hydroxyhexyl)-hydroquinone (formula III-2 wherein R=H3C, n=4, in the free form). The product was treated with ferric chloride in the same manner as Example 53 and then crystallized from diethyl ether. The procedure provided 2,3,5-trimethyl-6-(6'-hydroxyhexyl)-1,4-benzoquinone (formula IV-2, wherein R=H3C, n=4 in the free form) as yellow needles melting at 43°-45° C.
