실험 절차

To a solution of 4-dimethylaminomethylene-7-iodo-3,4-dihydro-1H-benzo[b]azepine-2,5-dione (v-a) (1.64 g, 4.6 mmol) in 50 mL EtOH was added K2CO3 (1.82 g, 11.04 mmol) and 1-(3,4-dimethoxyphenyl)guanidine (1.31 g, 5.06 mmol), and the reaction was heated to 80° C. for 12 h. The reaction was then cooled to 22° C., diluted with H2O, and treated with 1 M HCl to pH 3. The resulting solid was filtered and washed with H2O, followed by EtOH and Et2O. The crude product was dried in vacuo to give I-26 (1.8 g, 81%): HRMS Calcd. for C20H17IN4O3: 489.0423, Found 489.0431.
