Reaction Steps

In place of the 83.9 parts of 2-formylamino-3-carbamoyl-5-nitrothiophene used in Example 1 there are used 113.6 parts of 2-benzoylamino-3-carbamoyl-5-nitrothiophene, the first stage of the reaction being carried out for 15 minutes at 60° C. (instead of at 70°-75° C. as in Example 1). 2-Amino-3-cyano-5-nitrothiophene is obtained in an overall yield of 60%.
