In an article, published in an article,once mentioned the application of 21905-86-2,molecular formula is C9H6N2O2, is a conventional compound. this article was the specific content is as follows. 21905-86-2
A solution of cinnoline-4-carboxylic acid (183 mg, 1.02 mmol) in methylene chloride (20 ml) was reacted with EDCI (195 mg, 1.02 mmol) and HOBt (138 mg, 1.02 mmol) for 20 min and then stirred, together with 4b-amino-9b-hydroxy-7-isopropyl-4b,9b-dihydro-5-oxa-indeno[2,1-a]-inden-10-one (250 mg, 0.85 mmol), overnight at room temperature. After extraction with methylene chloride and water, the organic layer was dried over MgSO4 and concentrated in a vacuum. Purification by column chromatography (ethylacetate:n-hexane=1:1) afforded the title compound as a white solid (290 mg, 63%). [0846] 1H-NMR (300 MHz, CD3OD) delta 1.15 (d, J=6.8 Hz, 6H, CH3), 2.82 (sep, J=6.8 Hz, 1H, CH), 6.69 (s, 1H, ArH), 6.89 (d, J=7.8 Hz, 1H, ArH), 7.45 (d, J=7.9 Hz, 1H, ArH), 7.65 (m, 1H, ArH), 7.858.03 (m, 5H, ArH) 8.42 (d, J=8.0 Hz, 1H, ArH), 8.51 (d, J=8.4 Hz, 1H, ArH), 9.45 (s, 1H, ArH).
