To a solution of 6-bromo-2,3-dihydrophthalazine-1,4-dione (CAS 76240-49-8, 36.0 g, 150 mmol) and Et3N (37.5 g, 375 mmol) in DCM (1.0 L) was added Tf20 (42.3 g, 150 mol) dropwise over 1 h. The mixture was stirred at 0 C for 2 h and then kept at 15 C for 16 h. The mixture was filtered and the filtrate was concentrated. The residue was purified by flash column(petroleum ether: EtOAc from 5:1 to 3:1) to give a mixture of the title compounds (9.0 g, 16% yield) as a white solid.
76240-49-8 6-Bromophthalazine-1,4-diol 11379478, aphthalazine compound, is more and more widely used in various.
