Synthesis method

It is obtained by nitration and esterification of furfural. Add acetic anhydride to the reaction pot, cool it to -5°C, add 1/5 of the added amount of mixed acid (nitric acid and sulfuric acid) dropwise, and then add a mixture of nitric acid and furfural (1:2 volume) dropwise at the same time, and control the temperature at At about 0℃, after adding it for about 5-6 hours, continue to add a part of furfural dropwise. Then, stir for 1 hour, add water and sodium carbonate solution, raise the temperature to 55-62°C, and keep it warm for 1 hour. Cool to 15°C, filter, wash with water, and spin dry to obtain the finished product, with a yield of 85%.


It is a pharmaceutical intermediate, used in the preparation of furan anti-infective drugs (furatolin, nitrofuracillin, furantantine, etc.).
