Versuchsvorschrift

Methanesulfonyl chloride (0.3 g, 2.62 mmol) was added to a stirred suspension of 4-amino-2-[1-(3-ethoxy-4-methoxyphenyl)-2-(methylsulfonyl)-ethyl]isoindoline-1,3-dione (0.55 g, 1.31 mmol) and triethylamine (0.4 g, 3.93 mmol) in methylene chloride (60 mL) and the resulting mixture stirred for 24 hours. The mixture was then washed with sat. Sodium bicarbonate (25 mL), 1N hydrogen chloride (25 mL), H2O (25 mL), brine (25 mL) and dried over magnesium sulfate. The solvent was removed in vacuo. The residue was slurried in methanol:tetrahydrofuran (2:1) to give after isolation by filtration 4-[bis(methylsulfonyl)amino]-2-[1-(3-ethoxy-4-methoxyphenyl)-2-(methylsulfonyl)ethyl]isoindoline-1,3-dione (0.53 g, 70%) as a white solid: mp 277-279° C.; 1H NMR (DMSO-d6) δ8.05-7.95 (m, 3H), 7.11-6.92 (m, 3H), 5.78-5.74 (dd, J=5.5, 9.1 Hz, 1H), 4.31-4.22 (m, 2H), 3.99 (q, J=6.9 Hz, 2H), 3.73 (s, 3H), 3.55 (s, 6H), 2.95 (s, 3H), 1.31 (t, J=7.0 Hz, 3H); 13C NMR (DMSO-d6) δ166.11, 165.35, 148.96, 147.88, 138.63, 136.05, 132.60, 129.64, 129.31, 129.27, 125.26, 119.89, 112.33, 111.76, 63.73, 55.46, 53.38, 47.92, 43.50, 43.44, 41.15, 14.61; Anal.
