A mixture of furan-2,5-dicarboxylic acid monomethyl ester (1.95g) and 5% rhodium on carbon (400mg) in ethyl acetate (50ml) was hydrogenated until hydrogen uptake ceased. The catalyst was filtered off and washed with ethyl acetate. The combined filtrates were evaporated to give (2.00g) of the title compound: vmax (film) 3170, 1765 and 1720cm-1 ; δH (CDCl3) 1.95-2.65 (4H, m), 3.85 (3H, s) and 4.55-4.8 (2H, m).
