Versuchsvorschrift

To a solution of 13-bromo-N-[(1E)-(dimethylamino)methylidene]-9-oxa-3,6-diazatricyclo[8.4.0.02,6]tetradeca1(14),2,4,10,12-pentaene-4-carboxamide (2.2 g, 6.1 mmol) in AcOH (20 mL) was added isopropylhydrazine hydrochloride (0.73 g, 6.6 mmol). The mixture was heated at 100° C. for 1 h. Most of the solvent was removed and water (50 mL) was added. The solid was collected by filtration, washed with water and dried in vacuo to afford 13-Bromo-4-[1-(propan-2-yl)-1H-1,2,4-triazol-5-yl]-9-oxa-3,6-diazatricyclo[8.4.0.02,6]tetradeca1(14),2,4,10,12-pentaene, also named as 10-bromo-2-(1-isopropyl-1H-1,2,4-triazol-5-yl)-5,6-dihydrobenzo[f]imidazo[1,2-d][1,4]oxazepine (1.8 g, 74% yield) as a yellow solid. LCMS (ESI) m/z: 376.1 [M+H+].
