Versuchsvorschrift

(S)-4-(4-Chlorophenyl)-2,3,9-trimethyl-6H-thieno[3,2-f]-[1,2,4]triazolo[4,3-a][1,4]diazepine-6-acetic acid (3.0 g), triethylamine (1.56 ml) and p-phenylenediamine (0.97 g) are dissolved in dimethylformamide (30 ml). Benzotriazol-1-yl-oxy-tris(dimethyl)phosphonium hexafluorophosphate (3.6 g) is added, and the mixture is stirred at room temperature for 12 hours. After the completion of the reaction, water (200 ml) is added, and the mixture is extracted with ethyl acetate. The extract is washed with saturated brine and dried over anhydrous magnesium sulfate. After the solvent is distilled away under reduced pressure, the residue is subjected to silica gel column chromatography and obtained crystals are recrystallized from toluene to give 0.56 g of (S)-N-(4-aminophenyl)-4-(4-chlorophenyl)-2,3,9-trimethyl-6H-thieno[3,2-f][1,2,4]triazolo[4, 3-a][1,4]diazepine-6-acetamide, melting point 169°-173° C.
