tert-Butyl carbazate → 5-Methyl-2-furohydrazide

Participants

Reaction Steps

Tert-butyl carbazate (549 mg, 4.15 mmol) was added to a methylene chloride (10 mL) solution of commercially available 5-methylfuran-2-carbonyl chloride (500 mg, 3.46 mmol) under ice cooling, and the mixture was stirred at room temperature for 1 hour. The reaction solution was concentrated, and then, the residue was dissolved in methylene chloride (10 mL). To the solution, trifluoroacetic acid (2 mL) was added, and the mixture was stirred at room temperature for 1.5 hours. The reaction solution was concentrated to obtain 5-methylfuran-2-carbohydrazide.
