실험 절차

TEA (0.44 g, 4.4 mmol) was added to a mixture of 4-ethylbenzoyl chloride (0.34 g, 2.0 mmol) and 5-aminomethyl-2-[(3S)-3-methyl-2,6-dioxo-piperidin-3-yl]-isoindole-1,3-dione hydrochloride (0.67 g, 2.0 mmol) in acetonitrile (20 mL). The mixture was stirred at room temperature for 2 hours, and was evaporated under vacuum. The residue was partitioned between water (100 mL) and ethyl acetate (100 mL), and the organic phase was evaporated. The residue was chromatographed on silica gel using ethyl acetate as the mobile phase, providing 0.65 g, in 76% yield. The product was obtained as a white solid; mp 160-162° C.; HPLC, Waters Symmetry C-18, 3.9×150 mm, 5 μm, 1 mL/min, 240 nm, 45/55 CH3CN/0.1% H3PO4, 4.20 (97.47%); 1H NMR (DMSO-d6) δ 1.19 (t, J=7.7 Hz, 3H), 1.89 (s, 3H), 2.02-2.08 (m, 1H), 2.54-2.62 (m, 2H), 2.65-2.78 (m, 3H), 4.61 (d, J=6.0 Hz, 2H), 7.32 (d, J=8.1 Hz, 2H), 7.76-7.84 (m, 5H), 9.14 (t, J=6.0 Hz, 1H), 11.01 (s, 1H); 13C NMR (DMSO-d6) δ 15.4, 21.1, 28.1, 28.6, 29.2, 42.6, 58.8, 121.6, 123.2, 127.4, 127.8, 129.6, 131.4, 131.5, 133.4, 147.6, 147.7, 166.4, 167.8, 167.9, 172.2, 172.3; Anal.
