Versuchsvorschrift

To an anhydrous DMF (5 mL) solution of 5-(3-cyanophenyl)-8,9,10,11-tetrahydronaphtho[2,1-b][1,4]diazepine-2,4(3H,5H)-dione (302 mg, 0.91 mmol) was added tri-n-butyltin azide (499 μL, 1.82 mmol). The mixture was stirred at 110° C. for 24 hours. The reaction mixture was cooled on standing, poured into saturated aqueous sodium hydrogen carbonate solution, and washed with ethyl acetate. After neutralization of the aqueous layer by addition of 1M hydrochloric acid, the layer was extracted with ethyl acetate, washed with purified water, and dried over anhydrous sodium sulfate. The solvent was removed by evaporation under reduced pressure. The residue was purified by chromatography (chloroform/methanol=95/5) to give the titled compound as slightly yellow powder (242 mg, yield 71%).
