A mixture of 5-[4-(dimethylamino)butyl]-2-furanmethanol (4.9 g), acetic anhydride (25 g) and fused and powdered sodium acetate (10 g) in benzene (25 ml) was stirred at room temperature for 24 hr. The reaction was diluted with water (100 ml) and extracted with ethyl acetate. The combined extracts were distilled to afford a clear colourless oil b.p. 100°, 0.5 mm Hg. Found: C, 65.62; H, 9.03; N, 5.95. Calc. for C13H21NO3 : C, 65.24; H, 8.85; N, 5.85%.
