실험 절차

0.70 mol of N2,4-diphenylpyridine-2,3-diamine and 2.56 mol of ethoxymethylene malononitrile were added in 10 ml of isopropanol, and refluxed for 6 hours. The solution was removed and was purified by using column chromatography to thereby produce a solid crystalline product at a yield of 75%.
