To a mixture of 100 ml of trifluoroacetic anhydride and 100 ml of glacial acetic acid was added 89 g of 5-(2-furanyl)pentanol acetate in 100 ml of acetic acid. The reaction mixture was allowed to stand at room temperature for about 16 hours, then poured into water and extracted with methylene dichloride. The extracts were concentrated and the residue distilled to give 60.6 g of 5-(5-acetyl-2-furanyl)pentanol acetate, b.p. 120°-123° C. (0.05 mm).
