실험 절차

A mixture of ethyl thioxamate (10.55 g, 79.2 mmol) and formylhydrazine (5.00 g, 83.2 mmol) was heated at 65° C. for 30 minutes and stirred in accordance with a method described in Collect. Czech Chem. Commun., 1984, 49, p 2492. After cooling, the precipitated crystal was collected by filteration and washed with ethanol to give (N-formylhydrazino)-imino acetic acid ethyl ester (9.62 g). Yield: 76%.
