    The contemplated invention relates to the field of synthesis of biologically active substances, namely to the synthesis of an acetate derivative of the main water-soluble α-tocopherol metabolite known under the name of α-CEHC, which is prepared by the acid-catalyzed reaction of condensation of trimethyl hydroquinone with linalool in boiling octane, using n-toluenesulfonic acid or (+)-camphor-10-sulfonic acid as the catalyst. The reaction is carried out for 3 hours at the trimethyl hydroquinone:linalool:catalyst mole ratio of 1:1:0.1. The forming product is acetylated with acetic anhydride in pyridine at room temperature for 0.5 hour, and then ozonized in acetone in the presence of Ba(OH) 2 , oxidized with Jones' reagent in acetone, and isolated on silica gel column chromatography. Said compound is an acetate derivative of the main α-tocopherol metabolite—α-CEHC, for which high efficiency has been noted in treating disorders of the central nervous system.
