실험 절차

1,8-Diazabicyclo[5,4,0]undec-7-ene (0.620 g, 4.07 mmol) was added to a stirred suspension of 4-(aminomethyl)-2-(2,6-dioxo(3-piperidyl))-isoindoline-1,3-dione hydrochloride (0.600 g, 1.85 mmol) in CH3CN (50 ml). After stirring for 20 min, 2-thiophene-carbonyl chloride (0.3 g, 2.03 mmol) was added. The mixture was stirred at room temperature for 17 hours. The solvent was removed in vacuo and the residue was dissolved in CH2Cl2 (70 ml). The CH2Cl2 solution was washed with 1N HCl (30 ml), H2O (30 ml), brine (30 ml) and dried (MgSO4). The solvent was removed in vacuo and the residue was purified by chromatography (SiO2, CH2Cl2: EtOAc 6:4) to give N-{[2-(2,6-dioxo(3-piperidyl))-1,3-dioxoisoindolin-4-yl]methyl}-2-thienylcarboxamide (0.35 g, 47%) as a white solid: mp 192-194° C.; 1H NMR (DMSO-d6) δ d 11.16 (s, 1H), 9.18 (t, J=5.8 Hz, 1H), 7.88-7.72 (m 5H), 7.20-7.17 (dd, J=3.9 and 4.7 Hz, 1H), 5.22-5.15 (dd, J=5.5 and 12.7 Hz, 1H), 4.94 (d, J=5.8 Hz, 2H), 2.98-2.85 (m, 1H), 2.66-2.50 (m, 2H), 2.11-2.06 (m, 1H); 13C NMR (DMSO-d6) δ d 172.72, 169.80, 167.51, 166.93, 161.52, 139.26, 139.14, 134.83, 133.14, 131.53, 131.11, 128.51, 127.96, 127.12, 121.93, 48.89, 38.09, 30.93, 21.99; Anal.
