    • 1960, Clyde de Clifford Willson, Studies in the Pyrrole Series:
      The residue was now an amorphous powder, which could be almost completely dissolved in 250 cc. of warm methanol. This methanolic was treated with decolorizing charcoal, filtered, and concentrated, yielding small white cubic crystals,  […]
