실험 절차
A mixture of 5-methyl-2,4-dinitro-benzoic acid ethyl ester (39 g, 0.15 mol) and dimethoxymethyl-dimethylamine (32 g, 0.27 mol) in DMF (200 mL) was heated at 100° C. for 5 h. The mixture was poured into ice water. The precipitate was collected via filtration and washed with water to afford 5-(2-dimethylamino-vinyl)-2,4-dinitro-benzoic acid ethyl ester (15 g, 28%).
