Procedure

According to the same procedure as described in Preparation 1, hydroquinone and n-undecanoyl chloride (prepared by chlorination of n-undecanoic acid with thionyl chloride) were reacted and the reaction mixture was extracted with ethyl acetate. The ethyl acetate extract was concentrated and the residue was dissolved in n-hexane and crystallized with cooling to give crude hydroquinone monoundecanoate. The crude product was recrystallized from n-hexane. m.p. 72°-74° C.
