Versuchsvorschrift

8-Amino-quinoline-7-carbaldehyde 404 (100 mg, 0.58 mmol) and sulfamide (558 mg, 5.81 mmol) in pyridine (2 ml) was heated in a microwave at 140° C. for 2 h. After cooling, the mixture was concentrated in vacuo. The crude residue was dissolved in DCM and neutralised with citric acid. The resulting precipitate was collected by filtration and dried to give the title compound (111 mg, 82%) which was used in the next step without further purification.
