实验过程

2-[1-(3-Ethoxy-4-methoxyphenyl)-2-methylsulfonylethyl]-5-acetamidoisoindoline-1,3-dione was prepared by the procedure of Example 6 from 1-(3-ethoxy-4-methoxyphenyl)-2-methylsulfonylethylamine (1.0 g, 3.7 mmol) and 4-acetamidophthalic anhydride (751 mg, 3.66 mmol). The product was obtained as a yellow solid (330 mg, 20% yield): mp, 215.0-217.0° C.; 1H NMR (DMSO-d6) δ 1.32 (t, J=6.9 Hz, 3H, CH3), 2.12 (s, 3H, CH3), 2.99 (s, 3H, CH3), 3.73 (s, 3H, CH3), 4.00 (q, J=7.0 Hz, 2H, CH2), 4.12 (dd, J=4.5, 14.3 Hz, 1H, CHH), 4.35 (dd, J=10.5, 14.2 Hz, 1H, CHH), 5.76 (dd, J=4.5, 10.5 Hz, 1H, NCH), 6.90-6.98 (m, 2H, Ar), 7.08 (br s, 1H, Ar), 7.83-7.84 (m, 2H, Ar), 8.19 (br s, 1H, Ar), 10.95 (br s, 1H, NH); 13C NMR (DMSO-d6) δ 14.66, 24.22, 41.05, 47.35, 53.07, 55.47, 63.80, 111.74, 112.28, 112.72, 123.34, 124.59, 124.66, 129.74, 132.68, 145.00, 147.85, 148.84, 167.00, 167.28, 169.36; Anal Calcd for C22H24NO7S: C, 57.38; H, 5.25; N, 6.08. Found: C, 57.13; H, 5.18; N, 5.74.
