実験手順
A mixture of 5.9 g. of p-aminobenzonitrile and 9.5 g. of p-n-hexylbenzaldehyde in 100 ml. of benzene is treated with 150 mg. of p-toluenesulfonic acid and reacted as described in Example 1. After evaporation, there remain 14.4 g. of a brownish oil which crystallizes with cooling. Purification is carried out by several recrystallizations from isopropanol as described in Example 1. The p-[(p-n-hexylbenzyliden)amino]benzonitrile which is obtained has a melting point of 32.2°-33.0°C. and a clearing point of 64.5°C. UV (ethanol): ε281 = 23500 (shoulder at 310 nm). The nuclear magnetic resonance, mass spectrum, infrared and microanalysis data confirm the structure.
