Versuchsvorschrift

Methyl 10-bromo-3-(2-(cyclopropanecarbonyl)hydrazinecarbonyl)-6,7-dihydro-5H-5,7-methanobenzo[c]imidazo[1,2-a]azepine-2-carboxylate was dissolved in toluene (0.56 mL) and treated with Lawesson's reagent (1.3 equiv., 29.8 mg, 0.07359 mmol). The reaction was heated to reflux until judged complete by LC/MS analysis. The solution was cooled to room temperature. Water was added and the solution was extracted 2× with methylene chloride. The organic layers were combined, dried with sodium sulfate and concentrated in vacuo. The crude material was carried forward without further purification.
