Yield:108714-73-4 88%
Reaction Conditions:
with palladium on activated charcoal;hydrazine hydrate in ethanol for 4 h;Reflux;
Steps:
Preparation of 2-amino-9,9-dimethylfluorene (4):
10 g of 2-nitro-9,9-dimethylfluorene was added to the reaction flask, and stirred and dissolved with 80 m of ethanol.When 2-nitro-9,9-dimethylfluorene is completely dissolved into a clear solution,30 m L of hydrazine hydrate was added dropwise. After the addition was completed, 2 g of palladium on carbon catalyst was added, and then refluxed for 4 h. Finally, the color of the reaction liquid was very bright and dark red.Then directly hot filter,distillation under reduced pressure gave 7.7 g of a white solid, yield 88%, product content 99%.
