実験手順
To a solution of 13-bromo-9-oxa-3,6-diazatricyclo[8.4.0.02,6]tetradeca1(14),2,4,10,12-pentaene-4-carboxamide (2.0 g, 6.5 mmol) in dioxane (30 mL) was added DMF-DMA (2.6 mL, 19 mmol). The reaction mixture was heated at 100° C. for 1 h. The solvent was removed under reduce pressure and the residue was triturated with hot diethyl ether. The solid was collected by filtration, washed with diethyl ether and dried in vacuo to afford 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, 93% yield) as a yellow solid.
