실험 절차

To a solution of 5-nitroanthranilonitrile (1.00 g, 6.13 mmol) in dioxane (25 mL) was added dimethylformamide dimethylacetal (0.88 g, 7.36 mmol). The reaction mixture was stirred at 100° C. for 2 h and then cooled to room temperature and refrigerated. The precipitate was filtered out, washed with cold ether several times, and then dried in vacuo to give 1.30 g (97%) of (E)-N′-(2-cyano-4-nitrophenyl)-N,N-dimethylformamidine as a yellow solid.
