Reaktionsschritte

To a round-bottom flask was added a solution of diethyl oxalate (10.0 g, 68.4 mmol, 1.00 equiv) in ethanol (100 mL). Hydrazine hydrate (2.75 g, 85.8 mmol, 1.00 equiv) was added and the resulting mixture was stirred for 3 h at 80° C. After cooling to ambient temperature, the solids were removed via filtration and the filtrate was concentrated in vacuo to yield 8.00 g (80%) of the title compound as a colorless oil.
