Reaction Steps

2,4-Dimethyl-5-formylfuran-3-carboxylic acid ethyl ester (1.78 g, 9.1 mmol) reported in the references was dissolved in a mixture of acetic acid (32 ml) and water (8 ml). Amidosulfuric acid (1.19 g, 12.2 mmol) was added to the solution, and cooled to 0° C. in an ice bath. Sodium chlorite was added and stirred for 2 hours, and after addition of water to reaction mixture, precipitate was collected by filtration, thereby giving 3,5-dimethyl-4-ethoxycarbonylfuran-2-carboxylic acid (1.01 g, 52%) as a white solid.
