Hydrazine hydrate (1:1) → HCID 67041295, compound

Participants

Reaction Steps

A mixture of 2-{2-[3-(4-fluorophenyl)isoxazol-5-yl]ethyl}-1H-isoindole-1,3(2H)-dione (27.14 g, 80.70 mmol), hydrazine hydrate (9.8 mL, 202 mmol), and ethanol (700 mL) was heated at reflux under nitrogen for two hours. The reaction mixture was filtered to remove a solid, and the filtrate was concentrated under reduced pressure. The resulting oil was dissolved in ethyl acetate, and the solution was washed sequentially with water and brine, dried over sodium sulfate, filtered, and concentrated under reduced pressure to provide 16.14 g of 2-[3-(4-fluorophenyl)isoxazol-5-yl]ethylamine as a colorless oil.
