[0224] 4-Acetaminobenzaldehyde (2g, 0.0122mol) was dissolved in methanol (30ml), sodiummethoxide (0.85g, 0.0159mol) was added, and methyl azide acetate in methanol (1.65g, 0.0128mol) was added dropwise at room temperature, After dropping, react at room temperature for 1.5h. After the reaction was completed, the reaction solution was added to saturated ammoniumchloride solution, extracted with ethyl acetate (3×50ml), and the organic layers were combined. Wash the organic layer with saturated brine, anhydrous MgSO 4 Dry overnight. After filtration, the filtrate was evaporated under reduced pressure to remove the solvent, and the residue was passed through a column to obtain a pale yellow solid (2.7 g, 85%). Because the compound is unstable, it has not been characterized by NMR.
[0227] Compound 2a (2.7g, 0.0104mol) was dissolved in chlorobenzene (50ml) and heated to reflux for 2.5h. After the reaction was completed, a white solid precipitated out after cooling, and the target product was obtained by filtration, a white solid (2.08 g, 86%). 1 H-NMR(400M,DMSO-d 6 )δ(ppm): 2.05(s, 3H), 3.83(s, 3H), 7.07(s, 1H), 7.10(d, J=8.8Hz, 1H), 7.52(d, J=8.8Hz, 1H) ,8.01(s,1H),9.96(s,1H),11.75(s,1H).
[0230] Compound 3a (1g, 4.31mmol) was dissolved in a methanol solution of hydrogenchloride, and the mixture was heated to reflux for 2h. After the reaction was completed, the solvent was evaporated under pressure, and the residue was recrystallized from anhydrous methanol to obtain a white solid (0.37 g, 78%). 1 H-NMR(400M,DMSO-d 6 )δ(ppm): 3.87(s,3H), 6.94(d,J=8.4Hz,1H), 7.16(s,1H), 7.32(s,1H), 7.68(d,J=8.4Hz,1H) ,9.49(br,2H),11.99(s,1H).

Description
Technical field [0001] The present invention relates to a group of substituted benzoheterocyclic compounds and a synthesis method thereof, and also relates to the application of the compound in antiviral and antitumor aspects, a pharmaceutical composition containing the compound as an active component and the application thereof. Background technique [0002] During the extensive screening of antiviral active compounds, 4-benzyloxy-6-aminoindole-2-carboxylic acid methyl ester was found from the compound sample library established by the Pharmaceutical Biotechnology Laboratory of the Chinese Academy of Medical Sciences (as shown below ) It has obvious anti-influenza virus and anti-tumor activity. Previously, there was no literature report on any biological activity of this compound. This patent discovered the medicinal potential of the above compound for the first time. The present invention also uses this compound as a lead, designs and synthesizes a series of 2,3,4,5,6,7-positi...
