実験手順
15.1 g (67.4 mmols) of stilbene-4-carboxylic acid, 10.0 g (84.25 mmols) of thionyl chloride, 150 ml of toluene and 0.18 ml of N,N-dimethylformamide are stirred at 70° C. for 3 hours. The reaction mixture is then evaporated and the crude product is recrystallised from n-hexane/cyclohexane. 13.7 g (84% of theory) of stilbene-4-carboxylic acid chloride are obtained in the form of white crystals; melting point 131.2° C.
