57319-65-0,57319-65-0, 6-Aminoisobenzofuran-1(3H)-one is a benzofuran compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated

To a cooled solution (0 C) of 6-aminophthalide (5.13 g, 34.05 mmol) in THF (80 ml.) was added /V-bromosuccinimide (6.12 g, 34.05 mmol, 1 eq). The cooling bath was removed and the solution stirred for 1 h, then the solvent was removed under reduced pressure. The yellow residue was taken up in ethyl acetate (400 ml) and washed three times with water (200 ml. each). The organic phase was dried over magnesium sulfate, filtered and the solvent removed under reduced pressure to give 6-amino-7-bromophthalide as a brown solid (6.53 g, 28.63 mmol, 84%). Rf = 0.2 (cyclohexane/ethyl acetate 2:1 ); UPLC-MS: tR = 1.45 min (gradient 10-90% B in 5 min); UPLC-purity (210 nm) = 83.1%; ESI-MS: (calculated MH+: 227.97, 229.96, found: 228.01 , 230.01 )
