tert-Butylhydrazine monohydrochloride → HCID 19775373, compound

Participants

Reaction Steps

In a mixture of 60 ml of ethanol and 5 ml of triethylamine, 2.00 g (8.1 mmol) of Compound b and 2.00 g (16 mmol) of t-butylhydrazine hydrochloride were refluxed for 4 hours. The reaction mixture was dried under reduced pressure, and the residue was partitioned between chloroform and water. The chloroform layer was dried under reduced pressure, and the residue was passed through a silica gel column and eluted with a 3:1 (by volume) mixed solvent of hexane and ethyl acetate. The main fraction collected was dried under reduced pressure to obtain 2.11 g (87%) of Compound 7 as a colorless crystal. The product was treated with ethyl acetate saturated with hydrogen chloride to obtain a hydrochloride of Compound 7.
