実験手順
In 8 ml of N,N-dimethylformamide, 460 mg (2.25 mmol) of 7,7,8,8-tetracyanoquinodimethane was dissolved. With stirring under ice cooling, 500 mg (2.12 mmol) of dibutyl(3-methoxyphenyl)amine was dissolved in 2 ml of N,N-dimethylformamide and added dropwise. The mixture was stirred for 1.5 hours. After the ice bath was removed, the mixture was further stirred for 3.5 hours. After the reaction mixture was poured into 100 ml of water, extraction with ethyl acetate, washing with a saturated saline solution, drying over anhydrous sodium sulfate, and concentration were performed. The residue was purified by silica gel column chromatography and washed with chloroform to give 226 mg of an off-white crystal having a mp of 215-238° C. (yield: 25.6%).
