Vorschrift

1,5-Naphthalenediamine (0.791 g, 5 mM) was dissolved in 20 ml of ethyl acetate, and 2 equivalents of benzylisothiocyanate (1.492 g, 10 mM) were added. The mixture was stirred at 80° C. for 30 minutes. After cooling, the reaction mixture was filtered, and washed with ethylacetate/n-hexane to obtain 0.70 g (30.7% yield) of a colorless crystal of compound A-29.
