6296-53-3,6296-53-3, N-(1,3-Dioxo-1,3-dihydroisobenzofuran-4-yl)acetamide is a benzofuran compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
Example 1 Synthesis of 2-[1-(3-ethoxy-4-methoxyphenyl)-2-methylsulfonylethyl]-4-acetylaminoisoindoline-1,3-dione A stirred solution of 1-(3-ethoxy-4-methoxyphenyl)-methylsulfonylethylamine (1.0 g, 3.7 mmol) and 3-acetamidophthalic anhydride (751 mg, 3.66 mmol) in acetic acid (20 mL) was heated at reflux for 15 h. The solvent was removed in vacuo to yield an oil. Chromatography of the resulting oil yielded the product as a yellow solid (1.0 g, 59% yield): mp, 144 C.; 1H NMR (CDCl3) delta1.47 (t, J=7.0 Hz, 3H, CH3), 2.26 (s, 3H, CH3), 2.88 (s, 3H, CH3), 3.75 (dd, J=4.4, 14.3 Hz, 1H, CHH), 3.85 (s, 3H, CH3), 4.11 (q, J=7 Hz, 2H, CH2), 5.87 (dd, J=4.3, 10.5 Hz, 11-1, NCH), 6.82-6.86 (m, 1H, Ar), 7.09-7.11 (m, 2H, Ar), 7.47 (d, J=7 Hz, 1H, Ar), 7.64 (t, J=8 Hz, 1H, Ar), 8.74 (d, J=8 Hz, 1H, Ar), 9.49 (br s, 1H, NH); 13C NMR (CDCl3) delta14.61, 24.85, 41.54, 48.44, 54.34, 55.85, 64.43, 111.37, 112.34, 115.04, 118.11, 120.21, 124.85, 129.17, 130.96, 136.01, 137.52, 148.54, 149.65, 167.38, 169.09, 169.40; Anal Calc’d. for C22H24NO7S: C, 57.38; H, 5.25; N, 6.08. Found: C, 57.31; H, 5.34; N, 5.83.
The synthetic route of 6296-53-3 has been constantly updated, and we look forward to future research findings.
