실험 절차

TEA (0.28 g, 2.8 mmol) was added to a mixture of 3-(5-aminomethyl-1-oxo-1,3-dihydro-isoindol-2-yl)-piperidine-2,6-dione methanesulfonate (0.50 g, 1.4 mmol) and 3-chloro-4-methylphenyl isothiocyanate (0.26 g, 1.4 mmol) in acetonitrile (30 mL) at 0° C. The mixture was stirred at ambient temperature for 3 h and then 10% aqueous HCl solution (30 mL) was added. The solid precipitate was filtered and dried in vacuo providing 1-(3-chloro-4-methyl-phenyl)-3-[2-(2,6-dioxo-piperidin-3-yl)-1-oxo-2,3-dihydro-1H-isoindol-5-ylmethyl]-thiourea as a white solid (0.52 g, 84% yield); mp 240-242° C.; HPLC, Waters Symmetry C-18, 3.9×150 mm, 5 μm, 1 ml/min, 240 nm, 40/60 CH3CN/0.1% H3PO4, 7.11 (97.48%); 1H NMR (DMSO-d6) δ 1.95-2.06 (m, 1H, CHH), 2.29 (s, 3H, CH3), 2.35-2.47 (m, 1H, CHH), 2.55-2.67 (m, 1H, CHH), 2.84-3.00 (m, 1H, CHH), 4.32 (d, 1H, CHH), 4.46 (d, 1H, CHH), 4.86 (d, J=5.1 Hz, 2H, CH2 and CHH), 5.11 (dd, 1H, CH), 7.25 (dd, 1H, Ar), 7.28 (d, 1H, Ar), 7.47 (d, 1H, Ar), 7.54 (s, 1H, Ar), 7.61 (s, 1H, Ar), 7.70 (d, 1H, Ar), 8.37 (t, 1H, NH), 9.73 (s, 1H, NH), 11.00 (s, 1H, NH); 13C NMR (DMSO-d6) δ 18.96, 22.49, 31.20, 47.13, 51.58, 122.14, 122.88, 123.48, 127.13, 130.39, 130.97, 131.12, 132.67, 138.29, 142.27, 143.32, 167.92, 170.99, 172.86, 181.00; LCMS: MH=457/459; Anal.
