Participants

Reaction Steps

6.85 g of 7-deoxybaccatin III was dissolved in 250 ml of 95% ethanol, and 25 ml of hydrazine monohydrate was added thereto, followed by stirring at room temperature for 7 hours. Ethyl acetate was added to the reaction solution, the resulting mixture was washed successively with water and a saturated aqueous sodium chloride solution, and the organic layer was dried over anhydrous sodium sulfate. The solvent was evaporated under reduced pressure, and the resulting residue was purified by silica gel thin layer chromatography (a developing solvent; hexane:ethyl acetate=3:2 (v/v)) to yield 3.34 g of the titled compound as colorless crystals.
