Versuchsvorschrift

4,4'-Diaminobenzanilide (0.658 g, 2.5 mM) was dissolved in 20 ml of acetone, and 2 equivalents of phenylisothiocyanate (0.676 g, 5 mM) was added. The mixture was stirred at 55° C. for 10 minutes. After cooling, the reaction mixture was filtered, and washed with acetone/n-hexane to obtain 0.90 g (72.3% yield) of a colorless crystal of compound A-15.
