실험 절차

To a mixture containing 1-nitropropane (10.7 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 on addition of amine. Upon completion, the mixture is allowed to cool and then sit overnight.
