Reaction Steps

A solution of 1,9-Dihydro-1,3,4,9-tetraaza-fluorene-2-thione 14c (56 mmol, 1 equiv.) in hydrazine hydrate (195 mL) is heated to reflux (120° C.) for 4 hours as disclosed in Joshr, K. C.; Dandia, A.; Bawbia, S. J. Ind Chem. Soc. (1989), 66, 690-693 and references therein. The mixture is allowed to cool to room temperature for 48 hours. The orange-yellow precipitate is filtered, washed with water and ethanol, and dried under vacuum for 15 hours to yield (1,9-Dihydro-1,3,4,9-tetraaza-fluoren-2-ylidene)-hydrazine 14d as a yellow powder.
