Procedure

p-Phenylenediamine (2.707 g, 25 mM) was dissolved in 20 ml of ethyl acetate, and 2 equivalents of benzylisothiocyanate (7.461 g, 50 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 6.26 g (61.6% yield) of a colorless crystal of compound A-25.
