Procedure

To a solution of 6-(2'-hydroxy-3',4',6'-trimethylphenyl)hexanol (formula III-2, wherein R=H3C, X=H, Y=OH, n=4, in the free form) (0.02 part) in 1% sodium hydroxide solution (25 parts) was added Fremy's salt (0.2 part) at room temperature with stirring. After being stirred for 1 hour, the mixture was cooled to 0° C., acidified with dilute hydrochloric acid, and extracted with ethyl acetate. The extract was washed with water, dried over anhydrous sodium sulfate, and concentrated in vacuo to give 2,3,5-trimethyl-6-(6'-hydroxyhexyl)-1,4-benzoquinone (formula IV-2 wherein R=H3C, n=4, in the free form) (0.02 part) as yellow needles melting at 43°-45° C.
