실험 절차

A mixture of 1-tert-butyl-5-methyl-2,4-dinitrobenzene and 1-tert-butyl-3-methyl-2,4-dinitrobenzene (9.0 g, 38 mmol, 2:1 by NMR) and DMA (5.4 g, 45 mmol) in DMF (50 mL) was heated at reflux for 2 h before being cooled to room temperature. The reaction mixture was poured into water-ice and extracted with EtOAc (50 mL×3). The combined organic layers were washed with water and brine, before being evaporated to give a brown oil, which was purified by column to give (E)-2-(5-tert-butyl-2,4-dinitrophenyl)-N,N-dimethylethen-amine (5.0 g, 68%).
