110568-64-4, name is 6-Nitroisoindolin-1-one, belongs to indolines-derivatives compound, is considered to be a conventional heterocyclic compound, which is widely used in drug synthesis. The chemical synthesis route is as follows. Safety of 6-Nitroisoindolin-1-one
5-Amino-2,3-dihydroisoindol-l-oneH2N; [693] Iron powder (158mg, 2.83mmol), water (61uL), and HC1 (37%, 5uL,0.566mmol) were added into the suspension of 5-nitro-2,3-dihydroisoindol-l-one (50.4mg,0.283mmol) in EtOH (754|^L). The above mixture was heated at 95C for 2h. After thattime, several drops of 7N NH3 in MeOH were added to basify the solution, and the solid wasfiltered off. The filtrate was concentrated in vacua to obtain a light-yellow solid that waspurified by preparative TLC eluting with 10% MeOH/CH2Cl2 to give a light-yellow solid of5-amino-2,3-dihydroisoindol-l-one. ‘HNMR (CD3OD, 400 MHz): 5 = 7.48 (s, 1 H), 8.08 (s,2 H), 9.91 (s, 1 H), 10.66 (d, 1 H, J= 8.8 Hz). MS (ES+): m/z 149.21 (100) [MH1″]. HPLC: *R= 1.20 min (ZQ2000, polar_5 min).
The synthetic route of 110568-64-4 has been constantly updated, and we look forward to future research findings.
