1-Chloro-2,4-dinitrobenzene (1) was reacted with aliphatic amines (2) in ethanol as solvent under reflux condition for 16-24 h to form N-alkyl-2,4-dinitroaniline (3). Compound 3 undergoes reduction to from N-alkyl-4-nitrobenzene-1,2-diamine (4). Compound 4 was treated with carboxylic acid (5) to offered N-(2-(alkylamino)-5-nitrophenyl)-2-arylacetamide (6) which on cyclization gave 2-(arylmethyl)-1-ethyl-5-nitro-1H-benzo[d]imidazole (7). Finally, compound 7 undergoes reduction give 2-(arylmethyl)-1-ethyl-1H-benzo[d]imidazol-5-amine (8). The synthesized compounds were characterized by using spectral analyses. The compounds synthesized were confirmed by spectral analyses. Molecular docking of 5COX with the ligand using docking server, predicted the compound to be a potential anti-inflammatory compound.
1-氯-2,4-二硝基苯(1)与脂肪胺(2)在乙醇溶剂中反应,回流条件下反应16-24小时,形成N-烷基-2,4-二硝基苯胺(3)。化合物3经过还原反应生成N-烷基-4-硝基苯-1,2-二胺(4)。化合物4与羧酸(5)反应生成N-(2-(烷基氨基)-5-硝基苯基)-2-芳基乙酰胺(6),该化合物经过环化得到2-(芳基甲基)-1-乙基-5-硝基-1H-苯并[德]咪唑(7)。最后,化合物7经过还原反应生成2-(芳基甲基)-1-乙基-1H-苯并[德]咪唑-5-胺(8)。合成的化合物通过光谱分析进行了表征。合成的化合物得到了光谱分析的确认。使用对接服务器对5COX与配体进行分子对接,预测该化合物为潜在的抗炎化合物。
