실험 절차

To a mixture containing nitroethane (9.0 g., 0.12 moles), benzofuroxan (13.6 g., 0.10 moles) and tetrahydrofuran (50 ml.) is added dropwise diethylamine (8.7 g., 0.12 moles). The reaction temperature rises almost to reflux upon addition. Upon completion, the mixture is allowed to cool and to stand overnight.
