Participants

Reaction Steps

A 156 mg portion of sodium borohydride was added to a 10 ml methanol suspension of 280 mg N-(diaminomethylene)-8-oxo-8H-indeno[2,1-b]thiophene-6-carboxamide, followed by stirring at room temperature for 30 minutes. After evaporation of the solvent, the solid precipitated by adding water was purified by Chromatorex (DMF/chloroform) to obtain 284 mg of N-(diaminomethylene)-8-hydroxy-8H-indeno[2,1-b]thiophene-6-carboxamide as a pale green solid.
