Reaction Steps
A solution of 2-(2-amino-4-thiazolyl)malonic acid diethyl ester in a mixture of acetic anhydride (6 parts) and formic acid (6 parts) is stirred at 0° C. for 1 hour. The reaction mixture is concentrated in vacuum, diluted with ethyl acetate, washed with diluted hydrochloric acid, aqueous sodium hydrogen carbonate, and water, dried, and concentrated in vacuum to give 2-(2-formamido-4-thiazolyl)malonic acid diethyl ester. Yield: 70%.
