実験手順

2-Amino-4-nitrophenol (10 g, 65 mmole) and ethyl chloroacetimidate hydrochloride (15.4 g, 97.5 mmole) were heated at reflux temperature in ethanol (100 ml) for 18 hours. The solvent was then removed by evaporation in vacuo and the residue recrystallised from ethanol to give the title compound, yield 9.0 g, m.p. 216°-217°.
