实验过程

2-[1-(3-Ethoxy-4-methoxyphenyl)-2-methylsulfonylethyl]-4-acedtamidoisoindoline-1,3-dione was prepared by the procedure of Example 8 from 1-(3-ethoxy-4-methoxyphenyl)-2-methylsulfonylethylamine (1.0 g, 3.7 mmol) and 3-acetamidophthalic anhydride (751 mg, 3.66 mmol) in acetic acid (20 mL). The product was obtained as a yellow solid (1.0 g, 59% yield): mp, 144.0° C.; 1H NMR (CDCl3) δ 1.47 (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), 5.87 (dd, J=4.3, 10.5 Hz, 1H, NCH), 6.82-6.86 (m, 1H, Ar), 7.09-7.11 (m, 2H, Ar), 9.49 (br s, 1H, NH), 13C NMR (CDCl3) δ 14.61, 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 Calcd for C22H24NO7S: C, 57.38; H, 5.25; N, 6.08. Found: C, 57.31; H, 5.34; N, 5.83.
