Procedure

A solution of 5-methoxymethylfuran-2-carboxylic acid (3.10 g) in ethyl acetate (40 ml) was hydrogenated over 5% rhodium on carbon (200 mg) until hydrogen uptake ceased. The catalyst was filtered off and washed with ethyl acetate. The combined filtrates were evaporated to give the title compound as a colourless oil (3.26 g); νmax (film) 1750 cm-1 ; δH (CDCl3) 1.75-2.1 (2H,m), 2.1-2.6(2H,m,), 3.45 (3H,s), 3.47 (1H,dd, J 3 and 10 Hz), 3.74 (1H,dd, J 4 and 10 Hz), 4.15-4.43 (1H,m) and 4.43-4.63 (1H,m).
