실험 절차

2-(1-(2-hydroxyethyl)-2,6-dioxopiperidin-3-yl)isoindolin-1,3-dione (S)-2-(2-bromoacetamido)-3-methylbutanoate (120 mg) was dissolved in DCM (8 mL). The mixture was stirred and and diethylamine solution was added slowly dropwise (0.04 mL). The reaction mixture was stirred additionally for 2 hrs at room temperature. The solvent and the residual diethylamine were removed by rotary evaporation in vacuo. 101 mg of white solid were obtained after purification of the crude product by silica gel column chromatography (eluted with acetic ether: petroleum ether=3:1). 1H NMR (CDCl3, ppm) δ 7.94 (d, 1H, J=8.4 Hz), 7.87-7.91 (m, 2H), 7.76-7.79 (m, 2H), 4.97-5.08 (m, 1H), 4.38-4.43 (m, 1H), 4.05-4.30 (m, 3H), 3.25 (dd, 1H, J=4.8, 13.2Hz), 3.05 (s, 2H), 2.95-3.05 (m, 1H), 2.80-2.95 (m, 2H), 2.45-2.58 (m, 4H), 2.10-2.20 (m, 1H), 1.90-2.10 (m, 2H), 1.00-1.20 (m, 7H), 0.95-0.98 (m, 3H), 0.87-0.91 (m, 3H).
