Versuchsvorschrift
0.86 g of 1,2-diaminobenzene (o-phenylenediamine) is added to a solution of 1.4 g of 4-chloro-3-thienyl isothiocyanate in 40 ml of anhydrous THF, the mixture is stirred at room temperature for about 20 hours and the solvent is distilled off under reduced pressure. The residue is treated with water and extracted with ethyl acetate, the solvent is distilled off again and the residue is purified using medium-pressure silica gel column chromatography using a 1:1 mixture of ethyl acetate and toluene. Brown-yellow solid.
